We found the divisors of 745, 154, 445, 772 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 745, 154, 445, 772 is 1.

Therefore, GCD of numbers 745, 154, 445, 772 is 1

Given Input Data is 745, 154, 445, 772

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

Prime Factorization of 745 is 5 x 149

Prime Factorization of 154 is 2 x 7 x 11

Prime Factorization of 445 is 5 x 89

Prime Factorization of 772 is 2 x 2 x 193

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, 154) = 114730

GCD(745, 154) = ( 745 x 154 ) / 114730

GCD(745, 154) = 114730 / 114730

GCD(745, 154) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 445

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

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

GCD(1, 445) = 445 / 445

GCD(1, 445) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 772

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

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

GCD(1, 772) = 772 / 772

GCD(1, 772) = 1

GCD of 745, 154, 445, 772 is 1
