Make use of GCD Calculator to determine the Greatest Common Divisor of 355, 407, 811, 217 i.e. 1 largest integer that divides all the numbers equally.
GCD of 355, 407, 811, 217 is 1
GCD(355, 407, 811, 217) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 355, 407, 811, 217 is 1
GCD(355, 407, 811, 217) = 1
Given Input numbers are 355, 407, 811, 217
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 355, 407, 811, 217 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 355, 407, 811, 217 is 1.
Therefore, GCD of numbers 355, 407, 811, 217 is 1
Given Input Data is 355, 407, 811, 217
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 355 is 5 x 71
Prime Factorization of 407 is 11 x 37
Prime Factorization of 811 is 811
Prime Factorization of 217 is 7 x 31
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(355, 407) = 144485
GCD(355, 407) = ( 355 x 407 ) / 144485
GCD(355, 407) = 144485 / 144485
GCD(355, 407) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 811
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 811) = 811
GCD(1, 811) = ( 1 x 811 ) / 811
GCD(1, 811) = 811 / 811
GCD(1, 811) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 217
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 217) = 217
GCD(1, 217) = ( 1 x 217 ) / 217
GCD(1, 217) = 217 / 217
GCD(1, 217) = 1
GCD of 355, 407, 811, 217 is 1
