Given numbers are 780, 515, 200, 231

The list of prime factors of all numbers are

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

Prime factors of 515 are 5 x 103

Prime factors of 200 are 2 x 2 x 2 x 5 x 5

Prime factors of 231 are 3 x 7 x 11

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

Given numbers are 780, 515, 200, 231

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

Apply this formula for all numbers.

Step1:

LCM(780, 515) = 80340

GCD(780, 515) = ( 780 x 515 ) / 80340

= 780 / 515

= 780

Step2:

LCM(5, 200) = 200

GCD(5, 200) = ( 5 x 200 ) / 200

= 5 / 200

= 5

Step3:

LCM(5, 231) = 1155

GCD(5, 231) = ( 5 x 231 ) / 1155

= 5 / 231

= 5

So, Greatest Common Divisor of 780, 515, 200, 231 is 1
