Given numbers are 638, 130, 764, 454

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

Apply this formula for all numbers.

Step1:

LCM(638, 130) = 41470

GCD(638, 130) = ( 638 x 130 ) / 41470

= 638 / 130

= 638

Step2:

LCM(2, 764) = 764

GCD(2, 764) = ( 2 x 764 ) / 764

= 2 / 764

= 2

Step3:

LCM(2, 454) = 454

GCD(2, 454) = ( 2 x 454 ) / 454

= 2 / 454

= 2

So, Greatest Common Divisor of 638, 130, 764, 454 is 2
