Given numbers are 970, 645, 628, 664

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 628 are 2 x 2 x 157

Prime factors of 664 are 2 x 2 x 2 x 83

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

Given numbers are 970, 645, 628, 664

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, 628) = 3140

GCD(5, 628) = ( 5 x 628 ) / 3140

= 5 / 628

= 5

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 970, 645, 628, 664 is 1
