Therefore, GCD of numbers 423, 537, 715 is 1

Given Input Data is 423, 537, 715

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

Prime Factorization of 423 is 3 x 3 x 47

Prime Factorization of 537 is 3 x 179

Prime Factorization of 715 is 5 x 11 x 13

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(423, 537) = 75717

GCD(423, 537) = ( 423 x 537 ) / 75717

GCD(423, 537) = 227151 / 75717

GCD(423, 537) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 715

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

LCM(3, 715) = 2145

GCD(3, 715) = ( 3 x 715 ) / 2145

GCD(3, 715) = 2145 / 2145

GCD(3, 715) = 1

GCD of 423, 537, 715 is 1
