Given numbers are 855, 840, 89, 863

The list of prime factors of all numbers are

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 89 are 89

Prime factors of 863 are 863

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

Given numbers are 855, 840, 89, 863

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

Apply this formula for all numbers.

Step1:

LCM(855, 840) = 47880

GCD(855, 840) = ( 855 x 840 ) / 47880

= 855 / 840

= 855

Step2:

LCM(15, 89) = 1335

GCD(15, 89) = ( 15 x 89 ) / 1335

= 15 / 89

= 15

Step3:

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

= 1 / 863

= 1

So, Greatest Common Divisor of 855, 840, 89, 863 is 1
