Therefore, GCD of numbers 745, 140, 545, 191 is 1

Given Input Data is 745, 140, 545, 191

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

Prime Factorization of 745 is 5 x 149

Prime Factorization of 140 is 2 x 2 x 5 x 7

Prime Factorization of 545 is 5 x 109

Prime Factorization of 191 is 191

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, 140) = 20860

GCD(745, 140) = ( 745 x 140 ) / 20860

GCD(745, 140) = 104300 / 20860

GCD(745, 140) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 545

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

LCM(5, 545) = 545

GCD(5, 545) = ( 5 x 545 ) / 545

GCD(5, 545) = 2725 / 545

GCD(5, 545) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 191

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

LCM(5, 191) = 955

GCD(5, 191) = ( 5 x 191 ) / 955

GCD(5, 191) = 955 / 955

GCD(5, 191) = 1

GCD of 745, 140, 545, 191 is 1
