Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 455/12,817/664
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 455,817
Greatest Common Factor of Numerators i.e. GCF of 455,817 is 1 .
LCM of Denominators means LCM of 12,664 as per the given fractions.
LCM of 12,664 is 1992 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 455,817
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 455
List of positive integer factors of 455 that divides 455 without a remainder.
1,5,7,13,35,65,91,455
Factors of 817
List of positive integer factors of 817 that divides 817 without a remainder.
1,19,43,817
Greatest Common Factor
We found the factors 455,817 . The biggest common factor number is the GCF number.
So the greatest common factor 455,817 is 1.
Lets's calculate LCM of 12,664
2 | 12, 664 |
2 | 6, 332 |
3, 166 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 166 = 1992
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1992
Therefore, the GCF of Fractions 455/12,817/664 is 1/1992
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 12,664 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(12,664) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(12,664) x common factors =4 x 1 = 4
LCM(12,664) = ( 12 × 664 ) / 4
LCM(12,664) = 7968 / 4
LCM(12,664) = 1992
