Given numbers are 640, 404, 503, 196

The list of prime factors of all numbers are

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

Prime factors of 404 are 2 x 2 x 101

Prime factors of 503 are 503

Prime factors of 196 are 2 x 2 x 7 x 7

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

Given numbers are 640, 404, 503, 196

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

Apply this formula for all numbers.

Step1:

LCM(640, 404) = 64640

GCD(640, 404) = ( 640 x 404 ) / 64640

= 640 / 404

= 640

Step2:

LCM(4, 503) = 2012

GCD(4, 503) = ( 4 x 503 ) / 2012

= 4 / 503

= 4

Step3:

LCM(1, 196) = 196

GCD(1, 196) = ( 1 x 196 ) / 196

= 1 / 196

= 1

So, Greatest Common Divisor of 640, 404, 503, 196 is 1
