Given numbers are 560, 128, 347, 921

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 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 347 are 347

Prime factors of 921 are 3 x 307

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

Given numbers are 560, 128, 347, 921

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

Apply this formula for all numbers.

Step1:

LCM(560, 128) = 4480

GCD(560, 128) = ( 560 x 128 ) / 4480

= 560 / 128

= 560

Step2:

LCM(16, 347) = 5552

GCD(16, 347) = ( 16 x 347 ) / 5552

= 16 / 347

= 16

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 560, 128, 347, 921 is 1
