Therefore, GCD of numbers 618, 145, 62, 981 is 1

Given Input Data is 618, 145, 62, 981

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

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 145 is 5 x 29

Prime Factorization of 62 is 2 x 31

Prime Factorization of 981 is 3 x 3 x 109

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(618, 145) = 89610

GCD(618, 145) = ( 618 x 145 ) / 89610

GCD(618, 145) = 89610 / 89610

GCD(618, 145) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 62

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

LCM(1, 62) = 62

GCD(1, 62) = ( 1 x 62 ) / 62

GCD(1, 62) = 62 / 62

GCD(1, 62) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 981

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

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

GCD(1, 981) = 981 / 981

GCD(1, 981) = 1

GCD of 618, 145, 62, 981 is 1
