Given numbers are 677, 139, 618, 638

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

Apply this formula for all numbers.

Step1:

LCM(677, 139) = 94103

GCD(677, 139) = ( 677 x 139 ) / 94103

= 677 / 139

= 677

Step2:

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

= 1 / 618

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 677, 139, 618, 638 is 1
