Given numbers are 639, 441, 904, 684

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

Apply this formula for all numbers.

Step1:

LCM(639, 441) = 31311

GCD(639, 441) = ( 639 x 441 ) / 31311

= 639 / 441

= 639

Step2:

LCM(9, 904) = 8136

GCD(9, 904) = ( 9 x 904 ) / 8136

= 9 / 904

= 9

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 639, 441, 904, 684 is 1
