GCD of numbers is the greatest common divisor

So, the GCD (840, 828, 855, 308) = 1.

Given numbers are 840, 828, 855, 308

The list of prime factors of all numbers are

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

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

Prime factors of 308 are 2 x 2 x 7 x 11

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

Given numbers are 840, 828, 855, 308

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

Apply this formula for all numbers.

Step1:

LCM(840, 828) = 57960

GCD(840, 828) = ( 840 x 828 ) / 57960

= 840 / 828

= 840

Step2:

LCM(12, 855) = 3420

GCD(12, 855) = ( 12 x 855 ) / 3420

= 12 / 855

= 12

Step3:

LCM(3, 308) = 924

GCD(3, 308) = ( 3 x 308 ) / 924

= 3 / 308

= 3

So, Greatest Common Divisor of 840, 828, 855, 308 is 1
