Question

prove that 27,36 are not coprime​

Answer 1

Step-by-step explanation:

RULE: if two numbers have only 1 factor as common, then they are co-prime otherwise not.

i) 18 and 35

factors of 18: 1,2,3,6,9,18.

factors of 35: 1,5,7,35.

yes, they are co-prime numbers because only one factor is common that is 1.

ii) 15 and 37

factors of 15: 1,3,5,15.

factors of 35: 1,37.

yes, they are co-prime numbers because only one factor is common that is 1.
