Given numbers are 230, 497, 830, 420

The list of prime factors of all numbers are

Prime factors of 230 are 2 x 5 x 23

Prime factors of 497 are 7 x 71

Prime factors of 830 are 2 x 5 x 83

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

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

Given numbers are 230, 497, 830, 420

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

Apply this formula for all numbers.

Step1:

LCM(230, 497) = 114310

GCD(230, 497) = ( 230 x 497 ) / 114310

= 230 / 497

= 230

Step2:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 230, 497, 830, 420 is 1
