Given numbers are 664, 640, 580, 422

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

Apply this formula for all numbers.

Step1:

LCM(664, 640) = 53120

GCD(664, 640) = ( 664 x 640 ) / 53120

= 664 / 640

= 664

Step2:

LCM(8, 580) = 1160

GCD(8, 580) = ( 8 x 580 ) / 1160

= 8 / 580

= 8

Step3:

LCM(4, 422) = 844

GCD(4, 422) = ( 4 x 422 ) / 844

= 4 / 422

= 4

So, Greatest Common Divisor of 664, 640, 580, 422 is 2
