Given numbers are 639, 329, 601, 156

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

Apply this formula for all numbers.

Step1:

LCM(639, 329) = 210231

GCD(639, 329) = ( 639 x 329 ) / 210231

= 639 / 329

= 639

Step2:

LCM(1, 601) = 601

GCD(1, 601) = ( 1 x 601 ) / 601

= 1 / 601

= 1

Step3:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 639, 329, 601, 156 is 1
