Make use of GCD Calculator to determine the Greatest Common Divisor of 571, 562, 81, 155 i.e. 1 largest integer that divides all the numbers equally.
GCD of 571, 562, 81, 155 is 1
GCD(571, 562, 81, 155) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 571, 562, 81, 155 is 1
GCD(571, 562, 81, 155) = 1
Given Input numbers are 571, 562, 81, 155
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 571, 562, 81, 155 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 571, 562, 81, 155 is 1.
Therefore, GCD of numbers 571, 562, 81, 155 is 1
Given Input Data is 571, 562, 81, 155
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 571 is 571
Prime Factorization of 562 is 2 x 281
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 155 is 5 x 31
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(571, 562) = 320902
GCD(571, 562) = ( 571 x 562 ) / 320902
GCD(571, 562) = 320902 / 320902
GCD(571, 562) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 81
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
GCD(1, 81) = 81 / 81
GCD(1, 81) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 155
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
GCD(1, 155) = 155 / 155
GCD(1, 155) = 1
GCD of 571, 562, 81, 155 is 1
