Given numbers are 861, 442, 179, 403

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 442 are 2 x 13 x 17

Prime factors of 179 are 179

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 861, 442, 179, 403

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

Apply this formula for all numbers.

Step1:

LCM(861, 442) = 380562

GCD(861, 442) = ( 861 x 442 ) / 380562

= 861 / 442

= 861

Step2:

LCM(1, 179) = 179

GCD(1, 179) = ( 1 x 179 ) / 179

= 1 / 179

= 1

Step3:

LCM(1, 403) = 403

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

= 1 / 403

= 1

So, Greatest Common Divisor of 861, 442, 179, 403 is 1
