Given numbers are 309, 400, 496, 915

The list of prime factors of all numbers are

Prime factors of 309 are 3 x 103

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 496 are 2 x 2 x 2 x 2 x 31

Prime factors of 915 are 3 x 5 x 61

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

Given numbers are 309, 400, 496, 915

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

Apply this formula for all numbers.

Step1:

LCM(309, 400) = 123600

GCD(309, 400) = ( 309 x 400 ) / 123600

= 309 / 400

= 309

Step2:

LCM(1, 496) = 496

GCD(1, 496) = ( 1 x 496 ) / 496

= 1 / 496

= 1

Step3:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

So, Greatest Common Divisor of 309, 400, 496, 915 is 1
