Given numbers are 831, 129, 20

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

Apply this formula for all numbers.

Step1:

LCM(831, 129) = 35733

GCD(831, 129) = ( 831 x 129 ) / 35733

= 831 / 129

= 831

Step2:

LCM(3, 20) = 60

GCD(3, 20) = ( 3 x 20 ) / 60

= 3 / 20

= 3

So, Greatest Common Divisor of 831, 129, 20 is 1
