Therefore, GCD of numbers 10, 520, 373, 221 is 1

Given Input Data is 10, 520, 373, 221

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

Prime Factorization of 10 is 2 x 5

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

Prime Factorization of 373 is 373

Prime Factorization of 221 is 13 x 17

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(10, 520) = 520

GCD(10, 520) = ( 10 x 520 ) / 520

GCD(10, 520) = 5200 / 520

GCD(10, 520) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 373

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

LCM(10, 373) = 3730

GCD(10, 373) = ( 10 x 373 ) / 3730

GCD(10, 373) = 3730 / 3730

GCD(10, 373) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 221

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

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

GCD(1, 221) = 221 / 221

GCD(1, 221) = 1

GCD of 10, 520, 373, 221 is 1
