Given numbers are 638, 412, 353, 636

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

Apply this formula for all numbers.

Step1:

LCM(638, 412) = 131428

GCD(638, 412) = ( 638 x 412 ) / 131428

= 638 / 412

= 638

Step2:

LCM(2, 353) = 706

GCD(2, 353) = ( 2 x 353 ) / 706

= 2 / 353

= 2

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 638, 412, 353, 636 is 1
