Given numbers are 638, 189, 498, 207

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

Apply this formula for all numbers.

Step1:

LCM(638, 189) = 120582

GCD(638, 189) = ( 638 x 189 ) / 120582

= 638 / 189

= 638

Step2:

LCM(1, 498) = 498

GCD(1, 498) = ( 1 x 498 ) / 498

= 1 / 498

= 1

Step3:

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

= 1 / 207

= 1

So, Greatest Common Divisor of 638, 189, 498, 207 is 1
