Given numbers are 343, 780, 363, 815

The list of prime factors of all numbers are

Prime factors of 343 are 7 x 7 x 7

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 363 are 3 x 11 x 11

Prime factors of 815 are 5 x 163

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

Given numbers are 343, 780, 363, 815

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

Apply this formula for all numbers.

Step1:

LCM(343, 780) = 267540

GCD(343, 780) = ( 343 x 780 ) / 267540

= 343 / 780

= 343

Step2:

LCM(1, 363) = 363

GCD(1, 363) = ( 1 x 363 ) / 363

= 1 / 363

= 1

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 343, 780, 363, 815 is 1
