Given numbers are 129, 156, 169

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

Apply this formula for all numbers.

Step1:

LCM(129, 156) = 6708

GCD(129, 156) = ( 129 x 156 ) / 6708

= 129 / 156

= 129

Step2:

LCM(3, 169) = 507

GCD(3, 169) = ( 3 x 169 ) / 507

= 3 / 169

= 3

So, Greatest Common Divisor of 129, 156, 169 is 1
