Make use of GCD Calculator to determine the Greatest Common Divisor of 19, 7, 42, 99 i.e. 1 largest integer that divides all the numbers equally.
GCD of 19, 7, 42, 99 is 1
GCD(19, 7, 42, 99) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 19, 7, 42, 99 is 1
GCD(19, 7, 42, 99) = 1
Given Input numbers are 19, 7, 42, 99
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 19
List of positive integer divisors of 19 that divides 19 without a remainder.
1, 19
Divisors of 7

1, 7
Divisors of 42
List of positive integer divisors of 42 that divides 42 without a remainder.
1, 2, 3, 6, 7, 14, 21, 42
Divisors of 99
List of positive integer divisors of 99 that divides 99 without a remainder.
1, 3, 9, 11, 33, 99
Greatest Common Divisior
We found the divisors of 19, 7, 42, 99 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 19, 7, 42, 99 is 1.
Therefore, GCD of numbers 19, 7, 42, 99 is 1
Given Input Data is 19, 7, 42, 99
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 19 is 19
Prime Factorization of 7 is 7
Prime Factorization of 42 is 2 x 3 x 7
Prime Factorization of 99 is 3 x 3 x 11
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(19, 7) = 133
GCD(19, 7) = ( 19 x 7 ) / 133
GCD(19, 7) = 133 / 133
GCD(19, 7) = 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 99
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 99) = 99
GCD(1, 99) = ( 1 x 99 ) / 99
GCD(1, 99) = 99 / 99
GCD(1, 99) = 1
GCD of 19, 7, 42, 99 is 1
