Question

what is the hcf of 198 and 250​

Answer 1

Step-by-step explanation:

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

250 = 2 × 53;

250 is not a prime, is a composite number;

198 = 2 × 32 × 11;

198 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.

Answer 2

Answer:

250 = 2 × 53;

250 is not a prime, is a composite number;

198 = 2 × 32 × 11;

198 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 (250; 198) = 2
