Given Input Data is 147, 666, 486, 390

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

Prime Factorization of 147 is 3 x 7 x 7

Prime Factorization of 666 is 2 x 3 x 3 x 37

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

Prime Factorization of 390 is 2 x 3 x 5 x 13

Highest common occurrences in the given inputs are 3¹

Multiplying them we get the GCD as 3

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(147, 666) = 32634

GCD(147, 666) = ( 147 x 666 ) / 32634

GCD(147, 666) = 97902 / 32634

GCD(147, 666) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 486

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

LCM(3, 486) = 486

GCD(3, 486) = ( 3 x 486 ) / 486

GCD(3, 486) = 1458 / 486

GCD(3, 486) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 390

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

LCM(3, 390) = 390

GCD(3, 390) = ( 3 x 390 ) / 390

GCD(3, 390) = 1170 / 390

GCD(3, 390) = 3

GCD of 147, 666, 486, 390 is 3
