Make use of GCD Calculator to determine the Greatest Common Divisor of 51, 87, 17, 38 i.e. 1 largest integer that divides all the numbers equally.
GCD of 51, 87, 17, 38 is 1
GCD(51, 87, 17, 38) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 51, 87, 17, 38 is 1
GCD(51, 87, 17, 38) = 1
Given Input numbers are 51, 87, 17, 38
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 51

1, 3, 29, 87
Divisors of 17
List of positive integer divisors of 17 that divides 17 without a remainder.
1, 17
Divisors of 38
List of positive integer divisors of 38 that divides 38 without a remainder.
1, 2, 19, 38
Greatest Common Divisior
We found the divisors of 51, 87, 17, 38 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 51, 87, 17, 38 is 1.
Therefore, GCD of numbers 51, 87, 17, 38 is 1
Given Input Data is 51, 87, 17, 38
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 51 is 3 x 17
Prime Factorization of 87 is 3 x 29
Prime Factorization of 17 is 17
Prime Factorization of 38 is 2 x 19
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(51, 87) = 1479
GCD(51, 87) = ( 51 x 87 ) / 1479
GCD(51, 87) = 4437 / 1479
GCD(51, 87) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 17
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 17) = 51
GCD(3, 17) = ( 3 x 17 ) / 51
GCD(3, 17) = 51 / 51
GCD(3, 17) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 38
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 38) = 38
GCD(1, 38) = ( 1 x 38 ) / 38
GCD(1, 38) = 38 / 38
GCD(1, 38) = 1
GCD of 51, 87, 17, 38 is 1
