Given numbers are 420, 146, 391, 598

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 146 are 2 x 73

Prime factors of 391 are 17 x 23

Prime factors of 598 are 2 x 13 x 23

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

Given numbers are 420, 146, 391, 598

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

Apply this formula for all numbers.

Step1:

LCM(420, 146) = 30660

GCD(420, 146) = ( 420 x 146 ) / 30660

= 420 / 146

= 420

Step2:

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

= 2 / 391

= 2

Step3:

LCM(1, 598) = 598

GCD(1, 598) = ( 1 x 598 ) / 598

= 1 / 598

= 1

So, Greatest Common Divisor of 420, 146, 391, 598 is 1
