Make use of GCD Calculator to determine the Greatest Common Divisor of 47, 98, 55 i.e. 1 largest integer that divides all the numbers equally.
GCD of 47, 98, 55 is 1
GCD(47, 98, 55) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 47, 98, 55 is 1
GCD(47, 98, 55) = 1
Given Input numbers are 47, 98, 55
To find the GCD of numbers using factoring list out all the divisors of each number

1, 5, 11, 55
Greatest Common Divisior
We found the divisors of 47, 98, 55 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 47, 98, 55 is 1.
Therefore, GCD of numbers 47, 98, 55 is 1
Given Input Data is 47, 98, 55
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 47 is 47
Prime Factorization of 98 is 2 x 7 x 7
Prime Factorization of 55 is 5 x 11
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(47, 98) = 4606
GCD(47, 98) = ( 47 x 98 ) / 4606
GCD(47, 98) = 4606 / 4606
GCD(47, 98) = 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
GCD of 47, 98, 55 is 1
