Make use of GCD Calculator to determine the Greatest Common Divisor of 820, 165, 57, 211 i.e. 1 largest integer that divides all the numbers equally.
GCD of 820, 165, 57, 211 is 1
GCD(820, 165, 57, 211) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 820, 165, 57, 211 is 1
GCD(820, 165, 57, 211) = 1
Given Input numbers are 820, 165, 57, 211
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 820

1, 211
Greatest Common Divisior
We found the divisors of 820, 165, 57, 211 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 820, 165, 57, 211 is 1.
Therefore, GCD of numbers 820, 165, 57, 211 is 1
Given Input Data is 820, 165, 57, 211
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 165 is 3 x 5 x 11
Prime Factorization of 57 is 3 x 19
Prime Factorization of 211 is 211
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, 165) = 27060
GCD(820, 165) = ( 820 x 165 ) / 27060
GCD(820, 165) = 135300 / 27060
GCD(820, 165) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 57
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 57) = 285
GCD(5, 57) = ( 5 x 57 ) / 285
GCD(5, 57) = 285 / 285
GCD(5, 57) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 211
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 211) = 211
GCD(1, 211) = ( 1 x 211 ) / 211
GCD(1, 211) = 211 / 211
GCD(1, 211) = 1
GCD of 820, 165, 57, 211 is 1
