Given numbers are 285, 975, 451, 870

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 975 are 3 x 5 x 5 x 13

Prime factors of 451 are 11 x 41

Prime factors of 870 are 2 x 3 x 5 x 29

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

Given numbers are 285, 975, 451, 870

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

Apply this formula for all numbers.

Step1:

LCM(285, 975) = 18525

GCD(285, 975) = ( 285 x 975 ) / 18525

= 285 / 975

= 285

Step2:

LCM(15, 451) = 6765

GCD(15, 451) = ( 15 x 451 ) / 6765

= 15 / 451

= 15

Step3:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

So, Greatest Common Divisor of 285, 975, 451, 870 is 1
