$\huge\boxed{\fcolorbox{lightpink}{lime}{★A᭄ΠSWΣR✍︎}}$

Consider a set of two numbers, if they have no positive integer that can divide both, other than 1, the pair of numbers is co-prime.

Example 1: 21 and 22

For 21 and 22:

• The factors of 21 are 1, 3, 7, and 21.
• The factors of 22 are 1, 2, 11, and 22.
• Here 21 and 22 have only one common factor that is 1. Hence, their HCF is 1 and are co-prime.

Example 2: 21 and 27

For 21 and 27:

• The factors of 21 are 1, 3, 7, and 21.
• The factors of 27 are 1, 3, 9, and 27.
• Here 21 and 27 have two common factors; they are 1 and 3. HCF is 3 and they are not co-prime.

11=1,11

30=1,2,3,5,6,10,15

hence the common factor is 1

hope it will help u

Answer 2

Answer:

$1 1 = 1,11 \\ 30 = 1,2,3,5,6,10,15 \\ \\ the \: common \: factor \: is \: 1$
