Therefore, GCD of numbers 915, 705, 62, 509 is 1

Given Input Data is 915, 705, 62, 509

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

Prime Factorization of 915 is 3 x 5 x 61

Prime Factorization of 705 is 3 x 5 x 47

Prime Factorization of 62 is 2 x 31

Prime Factorization of 509 is 509

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(915, 705) = 43005

GCD(915, 705) = ( 915 x 705 ) / 43005

GCD(915, 705) = 645075 / 43005

GCD(915, 705) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 62

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

LCM(15, 62) = 930

GCD(15, 62) = ( 15 x 62 ) / 930

GCD(15, 62) = 930 / 930

GCD(15, 62) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 509

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

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

GCD(1, 509) = 509 / 509

GCD(1, 509) = 1

GCD of 915, 705, 62, 509 is 1
