Given numbers are 123, 615, 666

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

Apply this formula for all numbers.

Step1:

LCM(123, 615) = 615

GCD(123, 615) = ( 123 x 615 ) / 615

= 123 / 615

= 123

Step2:

LCM(123, 666) = 27306

GCD(123, 666) = ( 123 x 666 ) / 27306

= 123 / 666

= 123

So, Greatest Common Divisor of 123, 615, 666 is 3
