Therefore, GCD of numbers 220, 429, 86, 193 is 1

Given Input Data is 220, 429, 86, 193

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 429 is 3 x 11 x 13

Prime Factorization of 86 is 2 x 43

Prime Factorization of 193 is 193

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, 429) = 8580

GCD(220, 429) = ( 220 x 429 ) / 8580

GCD(220, 429) = 94380 / 8580

GCD(220, 429) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 86

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

LCM(11, 86) = 946

GCD(11, 86) = ( 11 x 86 ) / 946

GCD(11, 86) = 946 / 946

GCD(11, 86) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 193

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

LCM(1, 193) = 193

GCD(1, 193) = ( 1 x 193 ) / 193

GCD(1, 193) = 193 / 193

GCD(1, 193) = 1

GCD of 220, 429, 86, 193 is 1
