Given numbers are 520, 802, 78, 867

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 802 are 2 x 401

Prime factors of 78 are 2 x 3 x 13

Prime factors of 867 are 3 x 17 x 17

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

Given numbers are 520, 802, 78, 867

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

Apply this formula for all numbers.

Step1:

LCM(520, 802) = 208520

GCD(520, 802) = ( 520 x 802 ) / 208520

= 520 / 802

= 520

Step2:

LCM(2, 78) = 78

GCD(2, 78) = ( 2 x 78 ) / 78

= 2 / 78

= 2

Step3:

LCM(2, 867) = 1734

GCD(2, 867) = ( 2 x 867 ) / 1734

= 2 / 867

= 2

So, Greatest Common Divisor of 520, 802, 78, 867 is 1
