Given numbers are 891, 174, 630, 770

The list of prime factors of all numbers are

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

Prime factors of 174 are 2 x 3 x 29

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 891, 174, 630, 770

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

Apply this formula for all numbers.

Step1:

LCM(891, 174) = 51678

GCD(891, 174) = ( 891 x 174 ) / 51678

= 891 / 174

= 891

Step2:

LCM(3, 630) = 630

GCD(3, 630) = ( 3 x 630 ) / 630

= 3 / 630

= 3

Step3:

LCM(3, 770) = 2310

GCD(3, 770) = ( 3 x 770 ) / 2310

= 3 / 770

= 3

So, Greatest Common Divisor of 891, 174, 630, 770 is 1
