Given numbers are 638, 725, 863, 687

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

Apply this formula for all numbers.

Step1:

LCM(638, 725) = 15950

GCD(638, 725) = ( 638 x 725 ) / 15950

= 638 / 725

= 638

Step2:

LCM(29, 863) = 25027

GCD(29, 863) = ( 29 x 863 ) / 25027

= 29 / 863

= 29

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 638, 725, 863, 687 is 1
