Given numbers are 840, 243, 798, 830

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 830 are 2 x 5 x 83

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

Given numbers are 840, 243, 798, 830

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

Apply this formula for all numbers.

Step1:

LCM(840, 243) = 68040

GCD(840, 243) = ( 840 x 243 ) / 68040

= 840 / 243

= 840

Step2:

LCM(3, 798) = 798

GCD(3, 798) = ( 3 x 798 ) / 798

= 3 / 798

= 3

Step3:

LCM(3, 830) = 2490

GCD(3, 830) = ( 3 x 830 ) / 2490

= 3 / 830

= 3

So, Greatest Common Divisor of 840, 243, 798, 830 is 1
