Question

the HCF 39 and 91 finding common factors

Answer 1

39= 3×13 ( factors of 39).......... 91= 7×13( Factors of 91)......... 13 is common in both so HCF of 39 and 91 is 13...

Answer 2

Given : Numbers  39 and 91

To Find : common factors of the numbers

HCF

Solution:

Factors of 39  are 1 , 3 , 13 , 39

Factors  of 91  are  1 , 7 , 13 , 91

Common factor of 39 and 91 are  : 1 and 13

HCF = 1 * 13 = 13

HCF of 39 and 91  is 13

HCF Highest common factor of given numbers is the largest factors which divides all the given numbers perfectly.

HCF = product of common factors of least power
