Make use of GCD Calculator to determine the Greatest Common Divisor of 454, 721, 78, 436 i.e. 1 largest integer that divides all the numbers equally.
GCD of 454, 721, 78, 436 is 1
GCD(454, 721, 78, 436) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 454, 721, 78, 436 is 1
GCD(454, 721, 78, 436) = 1
Given Input numbers are 454, 721, 78, 436
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 454, 721, 78, 436 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 454, 721, 78, 436 is 1.
Therefore, GCD of numbers 454, 721, 78, 436 is 1
Given Input Data is 454, 721, 78, 436
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 454 is 2 x 227
Prime Factorization of 721 is 7 x 103
Prime Factorization of 78 is 2 x 3 x 13
Prime Factorization of 436 is 2 x 2 x 109
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(454, 721) = 327334
GCD(454, 721) = ( 454 x 721 ) / 327334
GCD(454, 721) = 327334 / 327334
GCD(454, 721) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 78
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 78) = 78
GCD(1, 78) = ( 1 x 78 ) / 78
GCD(1, 78) = 78 / 78
GCD(1, 78) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 436
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 436) = 436
GCD(1, 436) = ( 1 x 436 ) / 436
GCD(1, 436) = 436 / 436
GCD(1, 436) = 1
GCD of 454, 721, 78, 436 is 1
