Make use of GCD Calculator to determine the Greatest Common Divisor of 71, 5, 61, 28 i.e. 1 largest integer that divides all the numbers equally.
GCD of 71, 5, 61, 28 is 1
GCD(71, 5, 61, 28) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 71, 5, 61, 28 is 1
GCD(71, 5, 61, 28) = 1
Given Input numbers are 71, 5, 61, 28
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 71

1, 5
Divisors of 61
List of positive integer divisors of 61 that divides 61 without a remainder.
1, 61
Divisors of 28
List of positive integer divisors of 28 that divides 28 without a remainder.
1, 2, 4, 7, 14, 28
Greatest Common Divisior
We found the divisors of 71, 5, 61, 28 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 71, 5, 61, 28 is 1.
Therefore, GCD of numbers 71, 5, 61, 28 is 1
Given Input Data is 71, 5, 61, 28
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 71 is 71
Prime Factorization of 5 is 5
Prime Factorization of 61 is 61
Prime Factorization of 28 is 2 x 2 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(71, 5) = 355
GCD(71, 5) = ( 71 x 5 ) / 355
GCD(71, 5) = 355 / 355
GCD(71, 5) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 61
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 61) = 61
GCD(1, 61) = ( 1 x 61 ) / 61
GCD(1, 61) = 61 / 61
GCD(1, 61) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 28
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 28) = 28
GCD(1, 28) = ( 1 x 28 ) / 28
GCD(1, 28) = 28 / 28
GCD(1, 28) = 1
GCD of 71, 5, 61, 28 is 1
