Given numbers are 280, 696, 858, 891

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 696 are 2 x 2 x 2 x 3 x 29

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

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

Given numbers are 280, 696, 858, 891

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

Apply this formula for all numbers.

Step1:

LCM(280, 696) = 24360

GCD(280, 696) = ( 280 x 696 ) / 24360

= 280 / 696

= 280

Step2:

LCM(8, 858) = 3432

GCD(8, 858) = ( 8 x 858 ) / 3432

= 8 / 858

= 8

Step3:

LCM(2, 891) = 1782

GCD(2, 891) = ( 2 x 891 ) / 1782

= 2 / 891

= 2

So, Greatest Common Divisor of 280, 696, 858, 891 is 1
