So the Greatest Common Divisior 743, 430, 124, 188 is 1.

Therefore, GCD of numbers 743, 430, 124, 188 is 1

Given Input Data is 743, 430, 124, 188

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

Prime Factorization of 743 is 743

Prime Factorization of 430 is 2 x 5 x 43

Prime Factorization of 124 is 2 x 2 x 31

Prime Factorization of 188 is 2 x 2 x 47

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(743, 430) = 319490

GCD(743, 430) = ( 743 x 430 ) / 319490

GCD(743, 430) = 319490 / 319490

GCD(743, 430) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 124

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

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

GCD(1, 124) = 124 / 124

GCD(1, 124) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 188

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

LCM(1, 188) = 188

GCD(1, 188) = ( 1 x 188 ) / 188

GCD(1, 188) = 188 / 188

GCD(1, 188) = 1

GCD of 743, 430, 124, 188 is 1
