Given numbers are 309, 515, 375, 784

The list of prime factors of all numbers are

Prime factors of 309 are 3 x 103

Prime factors of 515 are 5 x 103

Prime factors of 375 are 3 x 5 x 5 x 5

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 309, 515, 375, 784

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

Apply this formula for all numbers.

Step1:

LCM(309, 515) = 1545

GCD(309, 515) = ( 309 x 515 ) / 1545

= 309 / 515

= 309

Step2:

LCM(103, 375) = 38625

GCD(103, 375) = ( 103 x 375 ) / 38625

= 103 / 375

= 103

Step3:

LCM(1, 784) = 784

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

= 1 / 784

= 1

So, Greatest Common Divisor of 309, 515, 375, 784 is 1
