Therefore, GCD of numbers 78, 891, 610, 325 is 1

Given Input Data is 78, 891, 610, 325

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11

Prime Factorization of 610 is 2 x 5 x 61

Prime Factorization of 325 is 5 x 5 x 13

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(78, 891) = 23166

GCD(78, 891) = ( 78 x 891 ) / 23166

GCD(78, 891) = 69498 / 23166

GCD(78, 891) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 610

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

LCM(3, 610) = 1830

GCD(3, 610) = ( 3 x 610 ) / 1830

GCD(3, 610) = 1830 / 1830

GCD(3, 610) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 325

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

LCM(1, 325) = 325

GCD(1, 325) = ( 1 x 325 ) / 325

GCD(1, 325) = 325 / 325

GCD(1, 325) = 1

GCD of 78, 891, 610, 325 is 1
