Make use of GCD Calculator to determine the Greatest Common Divisor of 430, 771, 842, 687 i.e. 1 largest integer that divides all the numbers equally.
GCD of 430, 771, 842, 687 is 1
GCD(430, 771, 842, 687) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 430, 771, 842, 687 is 1
GCD(430, 771, 842, 687) = 1
Given Input numbers are 430, 771, 842, 687
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 229, 687
Greatest Common Divisior
We found the divisors of 430, 771, 842, 687 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 430, 771, 842, 687 is 1.
Therefore, GCD of numbers 430, 771, 842, 687 is 1
Given Input Data is 430, 771, 842, 687
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 430 is 2 x 5 x 43
Prime Factorization of 771 is 3 x 257
Prime Factorization of 842 is 2 x 421
Prime Factorization of 687 is 3 x 229
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(430, 771) = 331530
GCD(430, 771) = ( 430 x 771 ) / 331530
GCD(430, 771) = 331530 / 331530
GCD(430, 771) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 842
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 842) = 842
GCD(1, 842) = ( 1 x 842 ) / 842
GCD(1, 842) = 842 / 842
GCD(1, 842) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 687
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
GCD(1, 687) = 687 / 687
GCD(1, 687) = 1
GCD of 430, 771, 842, 687 is 1
