Make use of GCD Calculator to determine the Greatest Common Divisor of 212, 547, 15, 403 i.e. 1 largest integer that divides all the numbers equally.
GCD of 212, 547, 15, 403 is 1
GCD(212, 547, 15, 403) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 212, 547, 15, 403 is 1
GCD(212, 547, 15, 403) = 1
Given Input numbers are 212, 547, 15, 403
To find the GCD of numbers using factoring list out all the divisors of each number

1, 13, 31, 403
Greatest Common Divisior
We found the divisors of 212, 547, 15, 403 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 212, 547, 15, 403 is 1.
Therefore, GCD of numbers 212, 547, 15, 403 is 1
Given Input Data is 212, 547, 15, 403
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 212 is 2 x 2 x 53
Prime Factorization of 547 is 547
Prime Factorization of 15 is 3 x 5
Prime Factorization of 403 is 13 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(212, 547) = 115964
GCD(212, 547) = ( 212 x 547 ) / 115964
GCD(212, 547) = 115964 / 115964
GCD(212, 547) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 15
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
GCD(1, 15) = 15 / 15
GCD(1, 15) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 403
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
GCD(1, 403) = 403 / 403
GCD(1, 403) = 1
GCD of 212, 547, 15, 403 is 1
