Given numbers are 756, 986, 455, 449

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 986 are 2 x 17 x 29

Prime factors of 455 are 5 x 7 x 13

Prime factors of 449 are 449

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

Given numbers are 756, 986, 455, 449

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

Apply this formula for all numbers.

Step1:

LCM(756, 986) = 372708

GCD(756, 986) = ( 756 x 986 ) / 372708

= 756 / 986

= 756

Step2:

LCM(2, 455) = 910

GCD(2, 455) = ( 2 x 455 ) / 910

= 2 / 455

= 2

Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

So, Greatest Common Divisor of 756, 986, 455, 449 is 1
