Make use of GCD Calculator to determine the Greatest Common Divisor of 971, 721, 42, 849 i.e. 1 largest integer that divides all the numbers equally.
GCD of 971, 721, 42, 849 is 1
GCD(971, 721, 42, 849) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 971, 721, 42, 849 is 1
GCD(971, 721, 42, 849) = 1
Given Input numbers are 971, 721, 42, 849
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 283, 849
Greatest Common Divisior
We found the divisors of 971, 721, 42, 849 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 971, 721, 42, 849 is 1.
Therefore, GCD of numbers 971, 721, 42, 849 is 1
Given Input Data is 971, 721, 42, 849
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 971 is 971
Prime Factorization of 721 is 7 x 103
Prime Factorization of 42 is 2 x 3 x 7
Prime Factorization of 849 is 3 x 283
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(971, 721) = 700091
GCD(971, 721) = ( 971 x 721 ) / 700091
GCD(971, 721) = 700091 / 700091
GCD(971, 721) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 42
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 42) = 42
GCD(1, 42) = ( 1 x 42 ) / 42
GCD(1, 42) = 42 / 42
GCD(1, 42) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 849
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 849) = 849
GCD(1, 849) = ( 1 x 849 ) / 849
GCD(1, 849) = 849 / 849
GCD(1, 849) = 1
GCD of 971, 721, 42, 849 is 1
