Given numbers are 970, 645, 770, 152

The list of prime factors of all numbers are

Prime factors of 970 are 2 x 5 x 97

Prime factors of 645 are 3 x 5 x 43

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

Prime factors of 152 are 2 x 2 x 2 x 19

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

Given numbers are 970, 645, 770, 152

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

Apply this formula for all numbers.

Step1:

LCM(970, 645) = 125130

GCD(970, 645) = ( 970 x 645 ) / 125130

= 970 / 645

= 970

Step2:

LCM(5, 770) = 770

GCD(5, 770) = ( 5 x 770 ) / 770

= 5 / 770

= 5

Step3:

LCM(5, 152) = 760

GCD(5, 152) = ( 5 x 152 ) / 760

= 5 / 152

= 5

So, Greatest Common Divisor of 970, 645, 770, 152 is 1
