Given numbers are 742, 988, 165, 770

The list of prime factors of all numbers are

Prime factors of 742 are 2 x 7 x 53

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 165 are 3 x 5 x 11

Prime factors of 770 are 2 x 5 x 7 x 11

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 742, 988, 165, 770

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(742, 988) = 366548

GCD(742, 988) = ( 742 x 988 ) / 366548

= 742 / 988

= 742

Step2:

LCM(2, 165) = 330

GCD(2, 165) = ( 2 x 165 ) / 330

= 2 / 165

= 2

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 742, 988, 165, 770 is 1
