Given numbers are 166, 617, 20

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

Apply this formula for all numbers.

Step1:

LCM(166, 617) = 102422

GCD(166, 617) = ( 166 x 617 ) / 102422

= 166 / 617

= 166

Step2:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

So, Greatest Common Divisor of 166, 617, 20 is 1
