Given numbers are 618, 840, 386, 637

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 386 are 2 x 193

Prime factors of 637 are 7 x 7 x 13

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 618, 840, 386, 637

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

Apply this formula for all numbers.

Step1:

LCM(618, 840) = 86520

GCD(618, 840) = ( 618 x 840 ) / 86520

= 618 / 840

= 618

Step2:

LCM(6, 386) = 1158

GCD(6, 386) = ( 6 x 386 ) / 1158

= 6 / 386

= 6

Step3:

LCM(2, 637) = 1274

GCD(2, 637) = ( 2 x 637 ) / 1274

= 2 / 637

= 2

So, Greatest Common Divisor of 618, 840, 386, 637 is 1
