Given numbers are 640, 874, 812, 277

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 874 are 2 x 19 x 23

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 277 are 277

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

Given numbers are 640, 874, 812, 277

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

Apply this formula for all numbers.

Step1:

LCM(640, 874) = 279680

GCD(640, 874) = ( 640 x 874 ) / 279680

= 640 / 874

= 640

Step2:

LCM(2, 812) = 812

GCD(2, 812) = ( 2 x 812 ) / 812

= 2 / 812

= 2

Step3:

LCM(2, 277) = 554

GCD(2, 277) = ( 2 x 277 ) / 554

= 2 / 277

= 2

So, Greatest Common Divisor of 640, 874, 812, 277 is 1
