Given numbers are 427, 460, 840, 256

The list of prime factors of all numbers are

Prime factors of 427 are 7 x 61

Prime factors of 460 are 2 x 2 x 5 x 23

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 427, 460, 840, 256

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

Apply this formula for all numbers.

Step1:

LCM(427, 460) = 196420

GCD(427, 460) = ( 427 x 460 ) / 196420

= 427 / 460

= 427

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

So, Greatest Common Divisor of 427, 460, 840, 256 is 1
