Given numbers are 287, 646, 175, 462

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 646 are 2 x 17 x 19

Prime factors of 175 are 5 x 5 x 7

Prime factors of 462 are 2 x 3 x 7 x 11

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

Given numbers are 287, 646, 175, 462

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

Apply this formula for all numbers.

Step1:

LCM(287, 646) = 185402

GCD(287, 646) = ( 287 x 646 ) / 185402

= 287 / 646

= 287

Step2:

LCM(1, 175) = 175

GCD(1, 175) = ( 1 x 175 ) / 175

= 1 / 175

= 1

Step3:

LCM(1, 462) = 462

GCD(1, 462) = ( 1 x 462 ) / 462

= 1 / 462

= 1

So, Greatest Common Divisor of 287, 646, 175, 462 is 1
