Therefore, GCD of numbers 390, 670, 43, 595 is 1

Given Input Data is 390, 670, 43, 595

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 670 is 2 x 5 x 67

Prime Factorization of 43 is 43

Prime Factorization of 595 is 5 x 7 x 17

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, 670) = 26130

GCD(390, 670) = ( 390 x 670 ) / 26130

GCD(390, 670) = 261300 / 26130

GCD(390, 670) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 43

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

LCM(10, 43) = 430

GCD(10, 43) = ( 10 x 43 ) / 430

GCD(10, 43) = 430 / 430

GCD(10, 43) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 595

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

LCM(1, 595) = 595

GCD(1, 595) = ( 1 x 595 ) / 595

GCD(1, 595) = 595 / 595

GCD(1, 595) = 1

GCD of 390, 670, 43, 595 is 1
