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

Apply this formula for all numbers.

Step1:

LCM(639, 213) = 639

GCD(639, 213) = ( 639 x 213 ) / 639

= 639 / 213

= 639

Step2:

LCM(213, 870) = 61770

GCD(213, 870) = ( 213 x 870 ) / 61770

= 213 / 870

= 213

Step3:

LCM(3, 282) = 282

GCD(3, 282) = ( 3 x 282 ) / 282

= 3 / 282

= 3

So, Greatest Common Divisor of 639, 213, 870, 282 is 3
