Make use of GCD Calculator to determine the Greatest Common Divisor of 845, 388, 31, 545 i.e. 1 largest integer that divides all the numbers equally.
GCD of 845, 388, 31, 545 is 1
GCD(845, 388, 31, 545) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 845, 388, 31, 545 is 1
GCD(845, 388, 31, 545) = 1
Given Input numbers are 845, 388, 31, 545
To find the GCD of numbers using factoring list out all the divisors of each number

1, 5, 109, 545
Greatest Common Divisior
We found the divisors of 845, 388, 31, 545 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 845, 388, 31, 545 is 1.
Therefore, GCD of numbers 845, 388, 31, 545 is 1
Given Input Data is 845, 388, 31, 545
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 845 is 5 x 13 x 13
Prime Factorization of 388 is 2 x 2 x 97
Prime Factorization of 31 is 31
Prime Factorization of 545 is 5 x 109
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(845, 388) = 327860
GCD(845, 388) = ( 845 x 388 ) / 327860
GCD(845, 388) = 327860 / 327860
GCD(845, 388) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 31
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 31) = 31
GCD(1, 31) = ( 1 x 31 ) / 31
GCD(1, 31) = 31 / 31
GCD(1, 31) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 545
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
GCD(1, 545) = 545 / 545
GCD(1, 545) = 1
GCD of 845, 388, 31, 545 is 1
