Question

What is the H.c.f of 105,153

Answer 1

Answer:

3 is the answer

Step-by-step explanation:

105 = 3 × 5 × 7;

105 is not a prime, is a composite number;

153 = 32 × 17;

153 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 (105; 153) = 3
