Therefore, GCD of numbers 220, 415, 93, 791 is 1

Given Input Data is 220, 415, 93, 791

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

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 415 is 5 x 83

Prime Factorization of 93 is 3 x 31

Prime Factorization of 791 is 7 x 113

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(220, 415) = 18260

GCD(220, 415) = ( 220 x 415 ) / 18260

GCD(220, 415) = 91300 / 18260

GCD(220, 415) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 93

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

LCM(5, 93) = 465

GCD(5, 93) = ( 5 x 93 ) / 465

GCD(5, 93) = 465 / 465

GCD(5, 93) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 791

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

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

GCD(1, 791) = 791 / 791

GCD(1, 791) = 1

GCD of 220, 415, 93, 791 is 1
