Given numbers are 420, 215, 183, 796

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 215 are 5 x 43

Prime factors of 183 are 3 x 61

Prime factors of 796 are 2 x 2 x 199

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

Given numbers are 420, 215, 183, 796

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

Apply this formula for all numbers.

Step1:

LCM(420, 215) = 18060

GCD(420, 215) = ( 420 x 215 ) / 18060

= 420 / 215

= 420

Step2:

LCM(5, 183) = 915

GCD(5, 183) = ( 5 x 183 ) / 915

= 5 / 183

= 5

Step3:

LCM(1, 796) = 796

GCD(1, 796) = ( 1 x 796 ) / 796

= 1 / 796

= 1

So, Greatest Common Divisor of 420, 215, 183, 796 is 1
