Make use of GCD Calculator to determine the Greatest Common Divisor of 272, 245, 55, 455 i.e. 1 largest integer that divides all the numbers equally.
GCD of 272, 245, 55, 455 is 1
GCD(272, 245, 55, 455) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 272, 245, 55, 455 is 1
GCD(272, 245, 55, 455) = 1
Given Input numbers are 272, 245, 55, 455
To find the GCD of numbers using factoring list out all the divisors of each number

1, 5, 7, 13, 35, 65, 91, 455
Greatest Common Divisior
We found the divisors of 272, 245, 55, 455 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 272, 245, 55, 455 is 1.
Therefore, GCD of numbers 272, 245, 55, 455 is 1
Given Input Data is 272, 245, 55, 455
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 272 is 2 x 2 x 2 x 2 x 17
Prime Factorization of 245 is 5 x 7 x 7
Prime Factorization of 55 is 5 x 11
Prime Factorization of 455 is 5 x 7 x 13
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(272, 245) = 66640
GCD(272, 245) = ( 272 x 245 ) / 66640
GCD(272, 245) = 66640 / 66640
GCD(272, 245) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 55
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 55) = 55
GCD(1, 55) = ( 1 x 55 ) / 55
GCD(1, 55) = 55 / 55
GCD(1, 55) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 455
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
GCD(1, 455) = 455 / 455
GCD(1, 455) = 1
GCD of 272, 245, 55, 455 is 1
