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

Apply this formula for all numbers.

Step1:

LCM(157, 615) = 96555

GCD(157, 615) = ( 157 x 615 ) / 96555

= 157 / 615

= 157

Step2:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 157, 615, 189 is 1
