Given numbers are 306, 387, 983, 515

The list of prime factors of all numbers are

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 387 are 3 x 3 x 43

Prime factors of 983 are 983

Prime factors of 515 are 5 x 103

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

Given numbers are 306, 387, 983, 515

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

Apply this formula for all numbers.

Step1:

LCM(306, 387) = 13158

GCD(306, 387) = ( 306 x 387 ) / 13158

= 306 / 387

= 306

Step2:

LCM(9, 983) = 8847

GCD(9, 983) = ( 9 x 983 ) / 8847

= 9 / 983

= 9

Step3:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

So, Greatest Common Divisor of 306, 387, 983, 515 is 1
