Given numbers are 129, 815, 357

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

Apply this formula for all numbers.

Step1:

LCM(129, 815) = 105135

GCD(129, 815) = ( 129 x 815 ) / 105135

= 129 / 815

= 129

Step2:

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

= 1 / 357

= 1

So, Greatest Common Divisor of 129, 815, 357 is 1
