Therefore, GCD of numbers 76, 740, 129, 155 is 1

Given Input Data is 76, 740, 129, 155

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

Prime Factorization of 76 is 2 x 2 x 19

Prime Factorization of 740 is 2 x 2 x 5 x 37

Prime Factorization of 129 is 3 x 43

Prime Factorization of 155 is 5 x 31

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(76, 740) = 14060

GCD(76, 740) = ( 76 x 740 ) / 14060

GCD(76, 740) = 56240 / 14060

GCD(76, 740) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 129

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

LCM(4, 129) = 516

GCD(4, 129) = ( 4 x 129 ) / 516

GCD(4, 129) = 516 / 516

GCD(4, 129) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 155

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

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

GCD(1, 155) = 155 / 155

GCD(1, 155) = 1

GCD of 76, 740, 129, 155 is 1
