To calculate the least common multiple (lcm) of decimals (integers)and fractions you first need to calculate the greatest commondivisor (gcd) of two integers:.int gcd (int a, int b) { int c; while (a !=0) { c=a; a=b % a; b=c; } return b; } With this function in place, we can calculate the...

squares have equal sides, so 15 + 15 + 15 + 15 or 15 x 4 she has to allow 1 cm for turning, so because its a square, she has to add 1 cm on each sides, so therefore 16 +16 + 16 +16 or 16 x 4 Then take that product and multiply it by 6 becasue she is making 6 of them (16 x 4) x 6 and that product is...

No, it is not a prime number.

No. The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24 because they all can be divided into 24 with no remainder.

Yes because it has only two factors which are itself and one

Determine the prime factors of both numbers. 400=2 x 2 x 2 x 2 x 5 x 5=2 4 x 5 2 120=2 x 2 x 2 x 3 x 5=2 3 x 3 x 5 The common factors are 2 3 and 5 : The highest common factor is 2 3 x 5=40. Common factors are formed from the individual common factors together with any combination...

There are several combinations, but this is one: 23 + 29=52.

The number one is far more special than a prime! It is the unit (the building block) of the positive integers, hence the only integer which merits its own existence axiom in Peano's axioms. It is the only multiplicative identity (1 . a=a . 1=a for all numbers a ). It is the only perfect ...

They are 59 and 61

The term originated from the Latin word primus , meaning first in importance. Prime are the important main ingredient of numbers, for every number greater than one is either a prime or a product of primes.

A composite number has at least one factor as well as 1 and itself. The factors of 50 are 1, 2, 5, 10, 25, and 50, so 50 must be a composite number. In other words, if it is not the number one, and it is positive, and it is not a prime number, it is a composite number.

The factor pairs of 98 are :- 1 x 98 2 x 49 7 x 14 The pairing that total 51 are 2 and 49.

That happens when one of the numbers is a multiple of the other.

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers. The greatest common factor of 30, 42, 48, and...

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers. The greatest common factor of 75 and 375 is 75

The greatest common factor of 17 and 119 is 17.

The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers. The least common multiple of 7, 10, and 18 is...

The LCM is 12.

Suppose not. Let p be prime and n=Sqrt[p]. Since p is an integer, if n is rational, then n is also an integer. So we have n.n=p. But since p is prime, only 1 and p divide p. ->

Terms in polynomials are simply separated by a plus or minus sign.For example, if you had: x+12x, that would be a binomial (twoterms). A trinomial is when the expression has three or more terms,7x+12x-6x.

4x + 3y + 3=4 ----> 4x=1 - 3y ----> x=0.25 - 0.75y----> 3y=1 - 4x ----> y=(1/3) - (4/3)x

All prime numbers are going to be deficient, because remember that a prime number's only factors are one and itself. To find if its deficient or abundant, you'd add up all of its factors, excluding itself. If its only other factor beside itself is one, that's obviously less than the number, and...
