What is the greatest common factor of 72 144 and 240?

Answer 1

To find the greatest common factor (GCF) of 72, 144, and 240, we first need to find the prime factorization of each number.

72 = 2^3 * 3^2 144 = 2^4 * 3^2 240 = 2^4 * 3 * 5

The GCF is the product of the common prime factors raised to the lowest power they appear in all the numbers. Therefore, the GCF of 72, 144, and 240 is 2^3 * 3 = 24.

Answer 2

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 72, 144, and 240 is 24
