Therefore, GCD of numbers 745, 343, 430 is 1

Given Input Data is 745, 343, 430

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

Prime Factorization of 745 is 5 x 149

Prime Factorization of 343 is 7 x 7 x 7

Prime Factorization of 430 is 2 x 5 x 43

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(745, 343) = 255535

GCD(745, 343) = ( 745 x 343 ) / 255535

GCD(745, 343) = 255535 / 255535

GCD(745, 343) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 430

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

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

GCD(1, 430) = 430 / 430

GCD(1, 430) = 1

GCD of 745, 343, 430 is 1
