Make use of GCD Calculator to determine the Greatest Common Divisor of 178, 746, 81, 349 i.e. 1 largest integer that divides all the numbers equally.
GCD of 178, 746, 81, 349 is 1
GCD(178, 746, 81, 349) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 178, 746, 81, 349 is 1
GCD(178, 746, 81, 349) = 1
Given Input numbers are 178, 746, 81, 349
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 178, 746, 81, 349 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 178, 746, 81, 349 is 1.
Therefore, GCD of numbers 178, 746, 81, 349 is 1
Given Input Data is 178, 746, 81, 349
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 178 is 2 x 89
Prime Factorization of 746 is 2 x 373
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 349 is 349
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(178, 746) = 66394
GCD(178, 746) = ( 178 x 746 ) / 66394
GCD(178, 746) = 132788 / 66394
GCD(178, 746) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 81
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 81) = 162
GCD(2, 81) = ( 2 x 81 ) / 162
GCD(2, 81) = 162 / 162
GCD(2, 81) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 349
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 349) = 349
GCD(1, 349) = ( 1 x 349 ) / 349
GCD(1, 349) = 349 / 349
GCD(1, 349) = 1
GCD of 178, 746, 81, 349 is 1
