Given numbers are 618, 820, 839, 403

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 839 are 839

Prime factors of 403 are 13 x 31

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

Given numbers are 618, 820, 839, 403

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

Apply this formula for all numbers.

Step1:

LCM(618, 820) = 253380

GCD(618, 820) = ( 618 x 820 ) / 253380

= 618 / 820

= 618

Step2:

LCM(2, 839) = 1678

GCD(2, 839) = ( 2 x 839 ) / 1678

= 2 / 839

= 2

Step3:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

So, Greatest Common Divisor of 618, 820, 839, 403 is 1
