Given numbers are 961, 940, 64, 630

The list of prime factors of all numbers are

Prime factors of 961 are 31 x 31

Prime factors of 940 are 2 x 2 x 5 x 47

Prime factors of 64 are 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 961, 940, 64, 630

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

Apply this formula for all numbers.

Step1:

LCM(961, 940) = 903340

GCD(961, 940) = ( 961 x 940 ) / 903340

= 961 / 940

= 961

Step2:

LCM(1, 64) = 64

GCD(1, 64) = ( 1 x 64 ) / 64

= 1 / 64

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 961, 940, 64, 630 is 1
