Greatest Common Divisior

We found the divisors of 13, 43, 70, 88 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 13, 43, 70, 88 is 1.

Therefore, GCD of numbers 13, 43, 70, 88 is 1

Given Input Data is 13, 43, 70, 88

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

Prime Factorization of 13 is 13

Prime Factorization of 43 is 43

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 88 is 2 x 2 x 2 x 11

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(13, 43) = 559

GCD(13, 43) = ( 13 x 43 ) / 559

GCD(13, 43) = 559 / 559

GCD(13, 43) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 70

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

LCM(1, 70) = 70

GCD(1, 70) = ( 1 x 70 ) / 70

GCD(1, 70) = 70 / 70

GCD(1, 70) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 88

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

LCM(1, 88) = 88

GCD(1, 88) = ( 1 x 88 ) / 88

GCD(1, 88) = 88 / 88

GCD(1, 88) = 1

GCD of 13, 43, 70, 88 is 1
