Given numbers are 826, 798, 861, 878

The list of prime factors of all numbers are

Prime factors of 826 are 2 x 7 x 59

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 861 are 3 x 7 x 41

Prime factors of 878 are 2 x 439

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

Given numbers are 826, 798, 861, 878

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

Apply this formula for all numbers.

Step1:

LCM(826, 798) = 47082

GCD(826, 798) = ( 826 x 798 ) / 47082

= 826 / 798

= 826

Step2:

LCM(14, 861) = 1722

GCD(14, 861) = ( 14 x 861 ) / 1722

= 14 / 861

= 14

Step3:

LCM(7, 878) = 6146

GCD(7, 878) = ( 7 x 878 ) / 6146

= 7 / 878

= 7

So, Greatest Common Divisor of 826, 798, 861, 878 is 1
