Given numbers are 458, 381, 638, 931

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

Apply this formula for all numbers.

Step1:

LCM(458, 381) = 174498

GCD(458, 381) = ( 458 x 381 ) / 174498

= 458 / 381

= 458

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

So, Greatest Common Divisor of 458, 381, 638, 931 is 1
