Given numbers are 731, 618, 129

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

Apply this formula for all numbers.

Step1:

LCM(731, 618) = 451758

GCD(731, 618) = ( 731 x 618 ) / 451758

= 731 / 618

= 731

Step2:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

So, Greatest Common Divisor of 731, 618, 129 is 1
