Given numbers are 618, 398, 639

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

Apply this formula for all numbers.

Step1:

LCM(618, 398) = 122982

GCD(618, 398) = ( 618 x 398 ) / 122982

= 618 / 398

= 618

Step2:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

So, Greatest Common Divisor of 618, 398, 639 is 1
