plz tell me 20 points or report it's your choice

Answer 1

HCF of 135and165

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

135 = 33 × 5;

135 is not a prime, is a composite number;

165 = 3 × 5 × 11;

165 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.

Calculate the greatest (highest) common factor (divisor), gcf, hcf, gcd:

Multiply all the common prime factors, by the lowest exponents (if any).

gcf, hcf, gcd (135; 165) = 3 × 5
