Given numbers are 638, 666, 171, 179

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

Apply this formula for all numbers.

Step1:

LCM(638, 666) = 212454

GCD(638, 666) = ( 638 x 666 ) / 212454

= 638 / 666

= 638

Step2:

LCM(2, 171) = 342

GCD(2, 171) = ( 2 x 171 ) / 342

= 2 / 171

= 2

Step3:

LCM(1, 179) = 179

GCD(1, 179) = ( 1 x 179 ) / 179

= 1 / 179

= 1

So, Greatest Common Divisor of 638, 666, 171, 179 is 1
