Given numbers are 420, 306, 582, 979

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 582 are 2 x 3 x 97

Prime factors of 979 are 11 x 89

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

Given numbers are 420, 306, 582, 979

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

Apply this formula for all numbers.

Step1:

LCM(420, 306) = 21420

GCD(420, 306) = ( 420 x 306 ) / 21420

= 420 / 306

= 420

Step2:

LCM(6, 582) = 582

GCD(6, 582) = ( 6 x 582 ) / 582

= 6 / 582

= 6

Step3:

LCM(6, 979) = 5874

GCD(6, 979) = ( 6 x 979 ) / 5874

= 6 / 979

= 6

So, Greatest Common Divisor of 420, 306, 582, 979 is 1
