Make use of GCD Calculator to determine the Greatest Common Divisor of 390, 242, 73, 913 i.e. 1 largest integer that divides all the numbers equally.
GCD of 390, 242, 73, 913 is 1
GCD(390, 242, 73, 913) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 390, 242, 73, 913 is 1
GCD(390, 242, 73, 913) = 1
Given Input numbers are 390, 242, 73, 913
To find the GCD of numbers using factoring list out all the divisors of each number

1, 73
Divisors of 913
List of positive integer divisors of 913 that divides 913 without a remainder.
1, 11, 83, 913
Greatest Common Divisior
We found the divisors of 390, 242, 73, 913 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 390, 242, 73, 913 is 1.
Therefore, GCD of numbers 390, 242, 73, 913 is 1
Given Input Data is 390, 242, 73, 913
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 390 is 2 x 3 x 5 x 13
Prime Factorization of 242 is 2 x 11 x 11
Prime Factorization of 73 is 73
Prime Factorization of 913 is 11 x 83
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(390, 242) = 47190
GCD(390, 242) = ( 390 x 242 ) / 47190
GCD(390, 242) = 94380 / 47190
GCD(390, 242) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 73
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 73) = 146
GCD(2, 73) = ( 2 x 73 ) / 146
GCD(2, 73) = 146 / 146
GCD(2, 73) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 913
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 913) = 913
GCD(1, 913) = ( 1 x 913 ) / 913
GCD(1, 913) = 913 / 913
GCD(1, 913) = 1
GCD of 390, 242, 73, 913 is 1
