Given numbers are 123, 372, 710, 649

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

Apply this formula for all numbers.

Step1:

LCM(123, 372) = 15252

GCD(123, 372) = ( 123 x 372 ) / 15252

= 123 / 372

= 123

Step2:

LCM(3, 710) = 2130

GCD(3, 710) = ( 3 x 710 ) / 2130

= 3 / 710

= 3

Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

So, Greatest Common Divisor of 123, 372, 710, 649 is 1
