Given Input Data is 975, 505, 90, 540

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

Prime Factorization of 975 is 3 x 5 x 5 x 13

Prime Factorization of 505 is 5 x 101

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

Prime Factorization of 540 is 2 x 2 x 3 x 3 x 3 x 5

Highest common occurrences in the given inputs are 5¹

Multiplying them we get the GCD as 5

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(975, 505) = 98475

GCD(975, 505) = ( 975 x 505 ) / 98475

GCD(975, 505) = 492375 / 98475

GCD(975, 505) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 90

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

LCM(5, 90) = 90

GCD(5, 90) = ( 5 x 90 ) / 90

GCD(5, 90) = 450 / 90

GCD(5, 90) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 540

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

LCM(5, 540) = 540

GCD(5, 540) = ( 5 x 540 ) / 540

GCD(5, 540) = 2700 / 540

GCD(5, 540) = 5

GCD of 975, 505, 90, 540 is 5
