who will don't know please don't give.​

Answer 1

Answer:

since 3 and 7 are prime number their H.C.F is 1

and since 7and 18 have no number common as prime factor , their HCF =1

Answer 2

Answer:

1- 1

2- 1

Step-by-step explanation:

1- we have to choose common factor of 3&7

3= 3*1

7= 7*1

so, common factor is 1

so, HCF is 1

2- similarly, factor of 7&18 is 1

so, HCF of 7&18 is 1
