Given numbers are 642, 969, 760, 957

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 969 are 3 x 17 x 19

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

Prime factors of 957 are 3 x 11 x 29

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

Given numbers are 642, 969, 760, 957

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

Apply this formula for all numbers.

Step1:

LCM(642, 969) = 207366

GCD(642, 969) = ( 642 x 969 ) / 207366

= 642 / 969

= 642

Step2:

LCM(3, 760) = 2280

GCD(3, 760) = ( 3 x 760 ) / 2280

= 3 / 760

= 3

Step3:

LCM(1, 957) = 957

GCD(1, 957) = ( 1 x 957 ) / 957

= 1 / 957

= 1

So, Greatest Common Divisor of 642, 969, 760, 957 is 1
