Make use of GCD Calculator to determine the Greatest Common Divisor of 720, 343, 521 i.e. 1 largest integer that divides all the numbers equally.
GCD of 720, 343, 521 is 1
GCD(720, 343, 521) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 720, 343, 521 is 1
GCD(720, 343, 521) = 1
Given Input numbers are 720, 343, 521
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 720

1, 7, 49, 343
Divisors of 521
List of positive integer divisors of 521 that divides 521 without a remainder.
1, 521
Greatest Common Divisior
We found the divisors of 720, 343, 521 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 720, 343, 521 is 1.
Therefore, GCD of numbers 720, 343, 521 is 1
Given Input Data is 720, 343, 521
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5
Prime Factorization of 343 is 7 x 7 x 7
Prime Factorization of 521 is 521
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(720, 343) = 246960
GCD(720, 343) = ( 720 x 343 ) / 246960
GCD(720, 343) = 246960 / 246960
GCD(720, 343) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 521
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 521) = 521
GCD(1, 521) = ( 1 x 521 ) / 521
GCD(1, 521) = 521 / 521
GCD(1, 521) = 1
GCD of 720, 343, 521 is 1
