The list of prime factors of all numbers are

Prime factors of 449 are 449

Prime factors of 286 are 2 x 11 x 13

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

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

Given numbers are 449, 286, 644, 560

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

Apply this formula for all numbers.

Step1:

LCM(449, 286) = 128414

GCD(449, 286) = ( 449 x 286 ) / 128414

= 449 / 286

= 449

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 560) = 560

GCD(1, 560) = ( 1 x 560 ) / 560

= 1 / 560

= 1

So, Greatest Common Divisor of 449, 286, 644, 560 is 1
