Given numbers are 284, 403, 868, 120

The list of prime factors of all numbers are

Prime factors of 284 are 2 x 2 x 71

Prime factors of 403 are 13 x 31

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

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

Given numbers are 284, 403, 868, 120

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

Apply this formula for all numbers.

Step1:

LCM(284, 403) = 114452

GCD(284, 403) = ( 284 x 403 ) / 114452

= 284 / 403

= 284

Step2:

LCM(1, 868) = 868

GCD(1, 868) = ( 1 x 868 ) / 868

= 1 / 868

= 1

Step3:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

So, Greatest Common Divisor of 284, 403, 868, 120 is 1
