Make use of GCD Calculator to determine the Greatest Common Divisor of 791, 820, 680 i.e. 1 largest integer that divides all the numbers equally.
GCD of 791, 820, 680 is 1
GCD(791, 820, 680) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 791, 820, 680 is 1
GCD(791, 820, 680) = 1
Given Input numbers are 791, 820, 680
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
Greatest Common Divisior
We found the divisors of 791, 820, 680 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 791, 820, 680 is 1.
Therefore, GCD of numbers 791, 820, 680 is 1
Given Input Data is 791, 820, 680
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 791 is 7 x 113
Prime Factorization of 820 is 2 x 2 x 5 x 41
Prime Factorization of 680 is 2 x 2 x 2 x 5 x 17
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(791, 820) = 648620
GCD(791, 820) = ( 791 x 820 ) / 648620
GCD(791, 820) = 648620 / 648620
GCD(791, 820) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 680
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
GCD(1, 680) = 680 / 680
GCD(1, 680) = 1
GCD of 791, 820, 680 is 1
