Given numbers are 639, 684, 410, 787

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

Apply this formula for all numbers.

Step1:

LCM(639, 684) = 48564

GCD(639, 684) = ( 639 x 684 ) / 48564

= 639 / 684

= 639

Step2:

LCM(9, 410) = 3690

GCD(9, 410) = ( 9 x 410 ) / 3690

= 9 / 410

= 9

Step3:

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

= 1 / 787

= 1

So, Greatest Common Divisor of 639, 684, 410, 787 is 1
