Question

21 and 24 are co primes​

Answer 1

Answer:

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

24 = 23 × 3;

24 is not a prime, is a composite number;

21 = 3 × 7;

21 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:

No

Step-by-step explanation:

21 has factors: 1, 3, 7, 21

24 has factors: 1, 2, 3, 4, 6, 8, 12, 24

since co prime numbers are those who has only 1 as a common factor but here 21 and 24 two common factors 1 and 3 => These are not co prime numbers.
