The list of prime factors of all numbers are

Prime factors of 487 are 487

Prime factors of 765 are 3 x 3 x 5 x 17

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

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

Given numbers are 487, 765, 870, 828

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

Apply this formula for all numbers.

Step1:

LCM(487, 765) = 372555

GCD(487, 765) = ( 487 x 765 ) / 372555

= 487 / 765

= 487

Step2:

LCM(1, 870) = 870

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

= 1 / 870

= 1

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 487, 765, 870, 828 is 1
