Given numbers are 635, 221, 935, 640

The list of prime factors of all numbers are

Prime factors of 635 are 5 x 127

Prime factors of 221 are 13 x 17

Prime factors of 935 are 5 x 11 x 17

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 635, 221, 935, 640

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

Apply this formula for all numbers.

Step1:

LCM(635, 221) = 140335

GCD(635, 221) = ( 635 x 221 ) / 140335

= 635 / 221

= 635

Step2:

LCM(1, 935) = 935

GCD(1, 935) = ( 1 x 935 ) / 935

= 1 / 935

= 1

Step3:

LCM(1, 640) = 640

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

= 1 / 640

= 1

So, Greatest Common Divisor of 635, 221, 935, 640 is 1
