Given numbers are 639, 242, 180, 463

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

Apply this formula for all numbers.

Step1:

LCM(639, 242) = 154638

GCD(639, 242) = ( 639 x 242 ) / 154638

= 639 / 242

= 639

Step2:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

Step3:

LCM(1, 463) = 463

GCD(1, 463) = ( 1 x 463 ) / 463

= 1 / 463

= 1

So, Greatest Common Divisor of 639, 242, 180, 463 is 1
