Given numbers are 631, 208, 222, 640

The list of prime factors of all numbers are

Prime factors of 631 are 631

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 222 are 2 x 3 x 37

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

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

Given numbers are 631, 208, 222, 640

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

Apply this formula for all numbers.

Step1:

LCM(631, 208) = 131248

GCD(631, 208) = ( 631 x 208 ) / 131248

= 631 / 208

= 631

Step2:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

Step3:

LCM(1, 640) = 640

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

= 1 / 640

= 1

So, Greatest Common Divisor of 631, 208, 222, 640 is 1
