Given numbers are 123, 516, 991

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

Apply this formula for all numbers.

Step1:

LCM(123, 516) = 21156

GCD(123, 516) = ( 123 x 516 ) / 21156

= 123 / 516

= 123

Step2:

LCM(3, 991) = 2973

GCD(3, 991) = ( 3 x 991 ) / 2973

= 3 / 991

= 3

So, Greatest Common Divisor of 123, 516, 991 is 1
