Given numbers are 638, 928, 414, 931

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

Apply this formula for all numbers.

Step1:

LCM(638, 928) = 10208

GCD(638, 928) = ( 638 x 928 ) / 10208

= 638 / 928

= 638

Step2:

LCM(58, 414) = 12006

GCD(58, 414) = ( 58 x 414 ) / 12006

= 58 / 414

= 58

Step3:

LCM(2, 931) = 1862

GCD(2, 931) = ( 2 x 931 ) / 1862

= 2 / 931

= 2

So, Greatest Common Divisor of 638, 928, 414, 931 is 1
