Given numbers are 730, 343, 813, 784

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 343 are 7 x 7 x 7

Prime factors of 813 are 3 x 271

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

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

Given numbers are 730, 343, 813, 784

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

Apply this formula for all numbers.

Step1:

LCM(730, 343) = 250390

GCD(730, 343) = ( 730 x 343 ) / 250390

= 730 / 343

= 730

Step2:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 730, 343, 813, 784 is 1
