Given numbers are 560, 313, 423, 257

The list of prime factors of all numbers are

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

Prime factors of 313 are 313

Prime factors of 423 are 3 x 3 x 47

Prime factors of 257 are 257

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

Given numbers are 560, 313, 423, 257

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

Apply this formula for all numbers.

Step1:

LCM(560, 313) = 175280

GCD(560, 313) = ( 560 x 313 ) / 175280

= 560 / 313

= 560

Step2:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 560, 313, 423, 257 is 1
