Answer 1

Answer:

H.C.F. by Long Division Method

We divide the bigger number by smaller one.

Divide smaller number in step 1 with remainder obtained in step 1.

Divide divisor of second step with remainder obtained in step 2.

Answer:

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

45 = 32 × 5;

45 is not a prime, is a composite number;

75 = 3 × 52;

75 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.
