Given numbers are 129, 631, 647, 187

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

Apply this formula for all numbers.

Step1:

LCM(129, 631) = 81399

GCD(129, 631) = ( 129 x 631 ) / 81399

= 129 / 631

= 129

Step2:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

Step3:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

So, Greatest Common Divisor of 129, 631, 647, 187 is 1
