Given numbers are 550, 640, 422, 631

The list of prime factors of all numbers are

Prime factors of 550 are 2 x 5 x 5 x 11

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

Prime factors of 422 are 2 x 211

Prime factors of 631 are 631

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

Given numbers are 550, 640, 422, 631

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

Apply this formula for all numbers.

Step1:

LCM(550, 640) = 35200

GCD(550, 640) = ( 550 x 640 ) / 35200

= 550 / 640

= 550

Step2:

LCM(10, 422) = 2110

GCD(10, 422) = ( 10 x 422 ) / 2110

= 10 / 422

= 10

Step3:

LCM(2, 631) = 1262

GCD(2, 631) = ( 2 x 631 ) / 1262

= 2 / 631

= 2

So, Greatest Common Divisor of 550, 640, 422, 631 is 1
