Question

Which of the is pair of co prime 20, 25


​

Answer 1

Answer:

both are not co prime

Step-by-step explanation:

number theory, two integers a and b are said to be relatively prime, mutually prime, or coprime (also written co-prime) if the only positive integer (factor) that divides both of them is 1. Consequently, any prime number that divides one does not divide the other.

Answer 2

Answer:

(i) 20,25

the factor of 20 is 2,4,5,10,20

the factor of 25 is 1,5

so there is not a co prime number
