Given numbers are 481, 478, 646, 287

The list of prime factors of all numbers are

Prime factors of 481 are 13 x 37

Prime factors of 478 are 2 x 239

Prime factors of 646 are 2 x 17 x 19

Prime factors of 287 are 7 x 41

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

Given numbers are 481, 478, 646, 287

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

Apply this formula for all numbers.

Step1:

LCM(481, 478) = 229918

GCD(481, 478) = ( 481 x 478 ) / 229918

= 481 / 478

= 481

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

So, Greatest Common Divisor of 481, 478, 646, 287 is 1
