Given numbers are 640, 468, 831, 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 468 are 2 x 2 x 3 x 3 x 13

Prime factors of 831 are 3 x 277

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, 468, 831, 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, 468) = 74880

GCD(640, 468) = ( 640 x 468 ) / 74880

= 640 / 468

= 640

Step2:

LCM(4, 831) = 3324

GCD(4, 831) = ( 4 x 831 ) / 3324

= 4 / 831

= 4

Step3:

LCM(1, 196) = 196

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

= 1 / 196

= 1

So, Greatest Common Divisor of 640, 468, 831, 196 is 1
