Given numbers are 129, 771, 36, 637

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

Apply this formula for all numbers.

Step1:

LCM(129, 771) = 33153

GCD(129, 771) = ( 129 x 771 ) / 33153

= 129 / 771

= 129

Step2:

LCM(3, 36) = 36

GCD(3, 36) = ( 3 x 36 ) / 36

= 3 / 36

= 3

Step3:

LCM(3, 637) = 1911

GCD(3, 637) = ( 3 x 637 ) / 1911

= 3 / 637

= 3

So, Greatest Common Divisor of 129, 771, 36, 637 is 1
