Make use of GCD Calculator to determine the Greatest Common Divisor of 307, 644, 91, 662 i.e. 1 largest integer that divides all the numbers equally.
GCD of 307, 644, 91, 662 is 1
GCD(307, 644, 91, 662) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 307, 644, 91, 662 is 1
GCD(307, 644, 91, 662) = 1
Given Input numbers are 307, 644, 91, 662
To find the GCD of numbers using factoring list out all the divisors of each number

1, 7, 13, 91
Divisors of 662
List of positive integer divisors of 662 that divides 662 without a remainder.
1, 2, 331, 662
Greatest Common Divisior
We found the divisors of 307, 644, 91, 662 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 307, 644, 91, 662 is 1.
Therefore, GCD of numbers 307, 644, 91, 662 is 1
Given Input Data is 307, 644, 91, 662
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 307 is 307
Prime Factorization of 644 is 2 x 2 x 7 x 23
Prime Factorization of 91 is 7 x 13
Prime Factorization of 662 is 2 x 331
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(307, 644) = 197708
GCD(307, 644) = ( 307 x 644 ) / 197708
GCD(307, 644) = 197708 / 197708
GCD(307, 644) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 91
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 91) = 91
GCD(1, 91) = ( 1 x 91 ) / 91
GCD(1, 91) = 91 / 91
GCD(1, 91) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 662
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 662) = 662
GCD(1, 662) = ( 1 x 662 ) / 662
GCD(1, 662) = 662 / 662
GCD(1, 662) = 1
GCD of 307, 644, 91, 662 is 1
