Therefore, GCD of numbers 545, 436, 61, 515 is 1

Given Input Data is 545, 436, 61, 515

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

Prime Factorization of 545 is 5 x 109

Prime Factorization of 436 is 2 x 2 x 109

Prime Factorization of 61 is 61

Prime Factorization of 515 is 5 x 103

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(545, 436) = 2180

GCD(545, 436) = ( 545 x 436 ) / 2180

GCD(545, 436) = 237620 / 2180

GCD(545, 436) = 109

Step2:

Here we consider the GCD from the above i.e. 109 as first number and the next as 61

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

LCM(109, 61) = 6649

GCD(109, 61) = ( 109 x 61 ) / 6649

GCD(109, 61) = 6649 / 6649

GCD(109, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 515

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

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

GCD(1, 515) = 515 / 515

GCD(1, 515) = 1

GCD of 545, 436, 61, 515 is 1
