Given numbers are 639, 166, 246, 458

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

Apply this formula for all numbers.

Step1:

LCM(639, 166) = 106074

GCD(639, 166) = ( 639 x 166 ) / 106074

= 639 / 166

= 639

Step2:

LCM(1, 246) = 246

GCD(1, 246) = ( 1 x 246 ) / 246

= 1 / 246

= 1

Step3:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

So, Greatest Common Divisor of 639, 166, 246, 458 is 1
