Make use of GCD Calculator to determine the Greatest Common Divisor of 820, 601, 122, 385 i.e. 1 largest integer that divides all the numbers equally.
GCD of 820, 601, 122, 385 is 1
GCD(820, 601, 122, 385) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 820, 601, 122, 385 is 1
GCD(820, 601, 122, 385) = 1
Given Input numbers are 820, 601, 122, 385
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 820, 601, 122, 385 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 820, 601, 122, 385 is 1.
Therefore, GCD of numbers 820, 601, 122, 385 is 1
Given Input Data is 820, 601, 122, 385
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 820 is 2 x 2 x 5 x 41
Prime Factorization of 601 is 601
Prime Factorization of 122 is 2 x 61
Prime Factorization of 385 is 5 x 7 x 11
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(820, 601) = 492820
GCD(820, 601) = ( 820 x 601 ) / 492820
GCD(820, 601) = 492820 / 492820
GCD(820, 601) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 122
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 122) = 122
GCD(1, 122) = ( 1 x 122 ) / 122
GCD(1, 122) = 122 / 122
GCD(1, 122) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 385
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
GCD(1, 385) = 385 / 385
GCD(1, 385) = 1
GCD of 820, 601, 122, 385 is 1
