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

Apply this formula for all numbers.

Step1:

LCM(123, 924) = 37884

GCD(123, 924) = ( 123 x 924 ) / 37884

= 123 / 924

= 123

Step2:

LCM(3, 915) = 915

GCD(3, 915) = ( 3 x 915 ) / 915

= 3 / 915

= 3

So, Greatest Common Divisor of 123, 924, 915 is 3
