Make use of GCD Calculator to determine the Greatest Common Divisor of 97, 48, 21 i.e. 1 largest integer that divides all the numbers equally.
GCD of 97, 48, 21 is 1
GCD(97, 48, 21) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 97, 48, 21 is 1
GCD(97, 48, 21) = 1
Given Input numbers are 97, 48, 21
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 97

Greatest Common Divisior
We found the divisors of 97, 48, 21 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 97, 48, 21 is 1.
Therefore, GCD of numbers 97, 48, 21 is 1
Given Input Data is 97, 48, 21
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 97 is 97
Prime Factorization of 48 is 2 x 2 x 2 x 2 x 3
Prime Factorization of 21 is 3 x 7
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(97, 48) = 4656
GCD(97, 48) = ( 97 x 48 ) / 4656
GCD(97, 48) = 4656 / 4656
GCD(97, 48) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 21
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
GCD(1, 21) = 21 / 21
GCD(1, 21) = 1
GCD of 97, 48, 21 is 1
