Given numbers are 639, 777, 123, 508

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

Apply this formula for all numbers.

Step1:

LCM(639, 777) = 165501

GCD(639, 777) = ( 639 x 777 ) / 165501

= 639 / 777

= 639

Step2:

LCM(3, 123) = 123

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

= 3 / 123

= 3

Step3:

LCM(3, 508) = 1524

GCD(3, 508) = ( 3 x 508 ) / 1524

= 3 / 508

= 3

So, Greatest Common Divisor of 639, 777, 123, 508 is 1
