Given numbers are 638, 496, 599, 221

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

Apply this formula for all numbers.

Step1:

LCM(638, 496) = 158224

GCD(638, 496) = ( 638 x 496 ) / 158224

= 638 / 496

= 638

Step2:

LCM(2, 599) = 1198

GCD(2, 599) = ( 2 x 599 ) / 1198

= 2 / 599

= 2

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 638, 496, 599, 221 is 1
