We found the divisors of 145, 716, 154, 749 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 145, 716, 154, 749 is 1.

Therefore, GCD of numbers 145, 716, 154, 749 is 1

Given Input Data is 145, 716, 154, 749

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

Prime Factorization of 145 is 5 x 29

Prime Factorization of 716 is 2 x 2 x 179

Prime Factorization of 154 is 2 x 7 x 11

Prime Factorization of 749 is 7 x 107

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(145, 716) = 103820

GCD(145, 716) = ( 145 x 716 ) / 103820

GCD(145, 716) = 103820 / 103820

GCD(145, 716) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 154

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

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

GCD(1, 154) = 154 / 154

GCD(1, 154) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 749

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

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

GCD(1, 749) = 749 / 749

GCD(1, 749) = 1

GCD of 145, 716, 154, 749 is 1
