Therefore, GCD of numbers 90, 618, 979, 545 is 1

Given Input Data is 90, 618, 979, 545

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

Prime Factorization of 90 is 2 x 3 x 3 x 5

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 979 is 11 x 89

Prime Factorization of 545 is 5 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(90, 618) = 9270

GCD(90, 618) = ( 90 x 618 ) / 9270

GCD(90, 618) = 55620 / 9270

GCD(90, 618) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 979

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

LCM(6, 979) = 5874

GCD(6, 979) = ( 6 x 979 ) / 5874

GCD(6, 979) = 5874 / 5874

GCD(6, 979) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 545

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

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

GCD(1, 545) = 545 / 545

GCD(1, 545) = 1

GCD of 90, 618, 979, 545 is 1
