Given numbers are 420, 819, 326, 707

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 819 are 3 x 3 x 7 x 13

Prime factors of 326 are 2 x 163

Prime factors of 707 are 7 x 101

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

Given numbers are 420, 819, 326, 707

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

Apply this formula for all numbers.

Step1:

LCM(420, 819) = 16380

GCD(420, 819) = ( 420 x 819 ) / 16380

= 420 / 819

= 420

Step2:

LCM(21, 326) = 6846

GCD(21, 326) = ( 21 x 326 ) / 6846

= 21 / 326

= 21

Step3:

LCM(1, 707) = 707

GCD(1, 707) = ( 1 x 707 ) / 707

= 1 / 707

= 1

So, Greatest Common Divisor of 420, 819, 326, 707 is 1
