240 = 2 x 2x2x2x3x5

1024 = 2 x 2x2x2x2x2x2x2x2x2

HCF = 2 x 2 x 2 x 2 = 16

Approach 1. Integer numbers prime factorization:

Prime Factorization of a number: finding the prime numbers that multiply together to make that number.

240 = 24 × 3 × 5;

240 is not a prime, is a composite number;

924 = 22 × 3 × 7 × 11;

924 is not a prime, is a composite number;

* Positive integers that are only dividing by themselves and 1 are called prime numbers. A prime number has only two factors: 1 and itself.

* A composite number is a positive integer that has at least one factor (divisor) other than 1 and itself.
