Given numbers are 630, 640, 961, 745

The list of prime factors of all numbers are

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

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 961 are 31 x 31

Prime factors of 745 are 5 x 149

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

Given numbers are 630, 640, 961, 745

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

Apply this formula for all numbers.

Step1:

LCM(630, 640) = 40320

GCD(630, 640) = ( 630 x 640 ) / 40320

= 630 / 640

= 630

Step2:

LCM(10, 961) = 9610

GCD(10, 961) = ( 10 x 961 ) / 9610

= 10 / 961

= 10

Step3:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

So, Greatest Common Divisor of 630, 640, 961, 745 is 1
