Given numbers are 531, 102, 123

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

Apply this formula for all numbers.

Step1:

LCM(531, 102) = 18054

GCD(531, 102) = ( 531 x 102 ) / 18054

= 531 / 102

= 531

Step2:

LCM(3, 123) = 123

GCD(3, 123) = ( 3 x 123 ) / 123

= 3 / 123

= 3

So, Greatest Common Divisor of 531, 102, 123 is 3
