Therefore, GCD of numbers 378, 207, 91, 486 is 1

Given Input Data is 378, 207, 91, 486

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

Prime Factorization of 378 is 2 x 3 x 3 x 3 x 7

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 91 is 7 x 13

Prime Factorization of 486 is 2 x 3 x 3 x 3 x 3 x 3

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(378, 207) = 8694

GCD(378, 207) = ( 378 x 207 ) / 8694

GCD(378, 207) = 78246 / 8694

GCD(378, 207) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 91

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

LCM(9, 91) = 819

GCD(9, 91) = ( 9 x 91 ) / 819

GCD(9, 91) = 819 / 819

GCD(9, 91) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 486

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

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

GCD(1, 486) = 486 / 486

GCD(1, 486) = 1

GCD of 378, 207, 91, 486 is 1
