Given numbers are 870, 728, 845, 487

The list of prime factors of all numbers are

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

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 845 are 5 x 13 x 13

Prime factors of 487 are 487

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

Given numbers are 870, 728, 845, 487

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

Apply this formula for all numbers.

Step1:

LCM(870, 728) = 316680

GCD(870, 728) = ( 870 x 728 ) / 316680

= 870 / 728

= 870

Step2:

LCM(2, 845) = 1690

GCD(2, 845) = ( 2 x 845 ) / 1690

= 2 / 845

= 2

Step3:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

So, Greatest Common Divisor of 870, 728, 845, 487 is 1
