Therefore, GCD of numbers 390, 275, 37, 403 is 1

Given Input Data is 390, 275, 37, 403

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

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

Prime Factorization of 275 is 5 x 5 x 11

Prime Factorization of 37 is 37

Prime Factorization of 403 is 13 x 31

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(390, 275) = 21450

GCD(390, 275) = ( 390 x 275 ) / 21450

GCD(390, 275) = 107250 / 21450

GCD(390, 275) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 37

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

LCM(5, 37) = 185

GCD(5, 37) = ( 5 x 37 ) / 185

GCD(5, 37) = 185 / 185

GCD(5, 37) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 403

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

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

GCD(1, 403) = 403 / 403

GCD(1, 403) = 1

GCD of 390, 275, 37, 403 is 1
