Given numbers are 639, 505, 204, 481

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

Apply this formula for all numbers.

Step1:

LCM(639, 505) = 322695

GCD(639, 505) = ( 639 x 505 ) / 322695

= 639 / 505

= 639

Step2:

LCM(1, 204) = 204

GCD(1, 204) = ( 1 x 204 ) / 204

= 1 / 204

= 1

Step3:

LCM(1, 481) = 481

GCD(1, 481) = ( 1 x 481 ) / 481

= 1 / 481

= 1

So, Greatest Common Divisor of 639, 505, 204, 481 is 1
