Given numbers are 870, 434, 817, 725

The list of prime factors of all numbers are

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

Prime factors of 434 are 2 x 7 x 31

Prime factors of 817 are 19 x 43

Prime factors of 725 are 5 x 5 x 29

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

Given numbers are 870, 434, 817, 725

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

Apply this formula for all numbers.

Step1:

LCM(870, 434) = 188790

GCD(870, 434) = ( 870 x 434 ) / 188790

= 870 / 434

= 870

Step2:

LCM(2, 817) = 1634

GCD(2, 817) = ( 2 x 817 ) / 1634

= 2 / 817

= 2

Step3:

LCM(1, 725) = 725

GCD(1, 725) = ( 1 x 725 ) / 725

= 1 / 725

= 1

So, Greatest Common Divisor of 870, 434, 817, 725 is 1
