Given numbers are 639, 387, 903, 377

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

Apply this formula for all numbers.

Step1:

LCM(639, 387) = 27477

GCD(639, 387) = ( 639 x 387 ) / 27477

= 639 / 387

= 639

Step2:

LCM(9, 903) = 2709

GCD(9, 903) = ( 9 x 903 ) / 2709

= 9 / 903

= 9

Step3:

LCM(3, 377) = 1131

GCD(3, 377) = ( 3 x 377 ) / 1131

= 3 / 377

= 3

So, Greatest Common Divisor of 639, 387, 903, 377 is 1
