Therefore, GCD of numbers 805, 975, 63, 745 is 1

Given Input Data is 805, 975, 63, 745

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

Prime Factorization of 805 is 5 x 7 x 23

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

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 745 is 5 x 149

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(805, 975) = 156975

GCD(805, 975) = ( 805 x 975 ) / 156975

GCD(805, 975) = 784875 / 156975

GCD(805, 975) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 63

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

LCM(5, 63) = 315

GCD(5, 63) = ( 5 x 63 ) / 315

GCD(5, 63) = 315 / 315

GCD(5, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 745

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

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

GCD(1, 745) = 745 / 745

GCD(1, 745) = 1

GCD of 805, 975, 63, 745 is 1
