Given numbers are 639, 399, 680, 736

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

Apply this formula for all numbers.

Step1:

LCM(639, 399) = 84987

GCD(639, 399) = ( 639 x 399 ) / 84987

= 639 / 399

= 639

Step2:

LCM(3, 680) = 2040

GCD(3, 680) = ( 3 x 680 ) / 2040

= 3 / 680

= 3

Step3:

LCM(1, 736) = 736

GCD(1, 736) = ( 1 x 736 ) / 736

= 1 / 736

= 1

So, Greatest Common Divisor of 639, 399, 680, 736 is 1
