Given numbers are 129, 990, 173, 101

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

Apply this formula for all numbers.

Step1:

LCM(129, 990) = 42570

GCD(129, 990) = ( 129 x 990 ) / 42570

= 129 / 990

= 129

Step2:

LCM(3, 173) = 519

GCD(3, 173) = ( 3 x 173 ) / 519

= 3 / 173

= 3

Step3:

LCM(1, 101) = 101

GCD(1, 101) = ( 1 x 101 ) / 101

= 1 / 101

= 1

So, Greatest Common Divisor of 129, 990, 173, 101 is 1
