Given numbers are 813, 390, 730, 849

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 730 are 2 x 5 x 73

Prime factors of 849 are 3 x 283

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

Given numbers are 813, 390, 730, 849

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

Apply this formula for all numbers.

Step1:

LCM(813, 390) = 105690

GCD(813, 390) = ( 813 x 390 ) / 105690

= 813 / 390

= 813

Step2:

LCM(3, 730) = 2190

GCD(3, 730) = ( 3 x 730 ) / 2190

= 3 / 730

= 3

Step3:

LCM(1, 849) = 849

GCD(1, 849) = ( 1 x 849 ) / 849

= 1 / 849

= 1

So, Greatest Common Divisor of 813, 390, 730, 849 is 1
