Given numbers are 639, 846, 200, 980

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

Apply this formula for all numbers.

Step1:

LCM(639, 846) = 60066

GCD(639, 846) = ( 639 x 846 ) / 60066

= 639 / 846

= 639

Step2:

LCM(9, 200) = 1800

GCD(9, 200) = ( 9 x 200 ) / 1800

= 9 / 200

= 9

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 639, 846, 200, 980 is 1
