Therefore, GCD of numbers 555, 474, 61, 785 is 1

Given Input Data is 555, 474, 61, 785

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

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 474 is 2 x 3 x 79

Prime Factorization of 61 is 61

Prime Factorization of 785 is 5 x 157

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(555, 474) = 87690

GCD(555, 474) = ( 555 x 474 ) / 87690

GCD(555, 474) = 263070 / 87690

GCD(555, 474) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 61

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

LCM(3, 61) = 183

GCD(3, 61) = ( 3 x 61 ) / 183

GCD(3, 61) = 183 / 183

GCD(3, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 785

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

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

GCD(1, 785) = 785 / 785

GCD(1, 785) = 1

GCD of 555, 474, 61, 785 is 1
