Given numbers are 478, 598, 668, 129

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

Apply this formula for all numbers.

Step1:

LCM(478, 598) = 142922

GCD(478, 598) = ( 478 x 598 ) / 142922

= 478 / 598

= 478

Step2:

LCM(2, 668) = 668

GCD(2, 668) = ( 2 x 668 ) / 668

= 2 / 668

= 2

Step3:

LCM(2, 129) = 258

GCD(2, 129) = ( 2 x 129 ) / 258

= 2 / 129

= 2

So, Greatest Common Divisor of 478, 598, 668, 129 is 1
