Given numbers are 309, 600, 817, 978

The list of prime factors of all numbers are

Prime factors of 309 are 3 x 103

Prime factors of 600 are 2 x 2 x 2 x 3 x 5 x 5

Prime factors of 817 are 19 x 43

Prime factors of 978 are 2 x 3 x 163

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

Given numbers are 309, 600, 817, 978

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

Apply this formula for all numbers.

Step1:

LCM(309, 600) = 61800

GCD(309, 600) = ( 309 x 600 ) / 61800

= 309 / 600

= 309

Step2:

LCM(3, 817) = 2451

GCD(3, 817) = ( 3 x 817 ) / 2451

= 3 / 817

= 3

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 309, 600, 817, 978 is 1
