Given numbers are 756, 309, 403, 356

The list of prime factors of all numbers are

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 309 are 3 x 103

Prime factors of 403 are 13 x 31

Prime factors of 356 are 2 x 2 x 89

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

Given numbers are 756, 309, 403, 356

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

Apply this formula for all numbers.

Step1:

LCM(756, 309) = 77868

GCD(756, 309) = ( 756 x 309 ) / 77868

= 756 / 309

= 756

Step2:

LCM(3, 403) = 1209

GCD(3, 403) = ( 3 x 403 ) / 1209

= 3 / 403

= 3

Step3:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

So, Greatest Common Divisor of 756, 309, 403, 356 is 1
