Given numbers are 870, 765, 442, 658

The list of prime factors of all numbers are

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

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

Prime factors of 442 are 2 x 13 x 17

Prime factors of 658 are 2 x 7 x 47

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

Given numbers are 870, 765, 442, 658

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

Apply this formula for all numbers.

Step1:

LCM(870, 765) = 44370

GCD(870, 765) = ( 870 x 765 ) / 44370

= 870 / 765

= 870

Step2:

LCM(15, 442) = 6630

GCD(15, 442) = ( 15 x 442 ) / 6630

= 15 / 442

= 15

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 870, 765, 442, 658 is 1
