Given numbers are 830, 249, 821, 322

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 249 are 3 x 83

Prime factors of 821 are 821

Prime factors of 322 are 2 x 7 x 23

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

Given numbers are 830, 249, 821, 322

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

Apply this formula for all numbers.

Step1:

LCM(830, 249) = 2490

GCD(830, 249) = ( 830 x 249 ) / 2490

= 830 / 249

= 830

Step2:

LCM(83, 821) = 68143

GCD(83, 821) = ( 83 x 821 ) / 68143

= 83 / 821

= 83

Step3:

LCM(1, 322) = 322

GCD(1, 322) = ( 1 x 322 ) / 322

= 1 / 322

= 1

So, Greatest Common Divisor of 830, 249, 821, 322 is 1
