Given numbers are 470, 682, 645, 868

The list of prime factors of all numbers are

Prime factors of 470 are 2 x 5 x 47

Prime factors of 682 are 2 x 11 x 31

Prime factors of 645 are 3 x 5 x 43

Prime factors of 868 are 2 x 2 x 7 x 31

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

Given numbers are 470, 682, 645, 868

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

Apply this formula for all numbers.

Step1:

LCM(470, 682) = 160270

GCD(470, 682) = ( 470 x 682 ) / 160270

= 470 / 682

= 470

Step2:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

Step3:

LCM(1, 868) = 868

GCD(1, 868) = ( 1 x 868 ) / 868

= 1 / 868

= 1

So, Greatest Common Divisor of 470, 682, 645, 868 is 1
