Given numbers are 815, 855, 922, 666

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

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

Prime factors of 922 are 2 x 461

Prime factors of 666 are 2 x 3 x 3 x 37

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

Given numbers are 815, 855, 922, 666

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

Apply this formula for all numbers.

Step1:

LCM(815, 855) = 139365

GCD(815, 855) = ( 815 x 855 ) / 139365

= 815 / 855

= 815

Step2:

LCM(5, 922) = 4610

GCD(5, 922) = ( 5 x 922 ) / 4610

= 5 / 922

= 5

Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

So, Greatest Common Divisor of 815, 855, 922, 666 is 1
