Given numbers are 631, 185, 640, 904

The list of prime factors of all numbers are

Prime factors of 631 are 631

Prime factors of 185 are 5 x 37

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

Prime factors of 904 are 2 x 2 x 2 x 113

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

Given numbers are 631, 185, 640, 904

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

Apply this formula for all numbers.

Step1:

LCM(631, 185) = 116735

GCD(631, 185) = ( 631 x 185 ) / 116735

= 631 / 185

= 631

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

= 1 / 904

= 1

So, Greatest Common Divisor of 631, 185, 640, 904 is 1
