Given numbers are 875, 687, 664, 621

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

Apply this formula for all numbers.

Step1:

LCM(875, 687) = 601125

GCD(875, 687) = ( 875 x 687 ) / 601125

= 875 / 687

= 875

Step2:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 875, 687, 664, 621 is 1
