Given numbers are 639, 885, 630, 994

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

Apply this formula for all numbers.

Step1:

LCM(639, 885) = 188505

GCD(639, 885) = ( 639 x 885 ) / 188505

= 639 / 885

= 639

Step2:

LCM(3, 630) = 630

GCD(3, 630) = ( 3 x 630 ) / 630

= 3 / 630

= 3

Step3:

LCM(3, 994) = 2982

GCD(3, 994) = ( 3 x 994 ) / 2982

= 3 / 994

= 3

So, Greatest Common Divisor of 639, 885, 630, 994 is 1
