Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 27/665,84/257
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 27,84
Greatest Common Factor of Numerators i.e. GCF of 27,84 is 3 .
LCM of Denominators means LCM of 665,257 as per the given fractions.
LCM of 665,257 is 170905 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 27,84
3 | 27, 84 |
9, 28 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 27
List of positive integer factors of 27 that divides 27 without a remainder.
1,3,9,27
Factors of 84
List of positive integer factors of 84 that divides 84 without a remainder.
1,2,3,4,6,7,12,14,21,28,42,84
Greatest Common Factor
We found the factors 27,84 . The biggest common factor number is the GCF number.
So the greatest common factor 27,84 is 3.
Lets's calculate LCM of 665,257
Given numbers has no common factors except 1. So, there LCM is their product i.e 170905
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/170905
Therefore, the GCF of Fractions 27/665,84/257 is 3/170905
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 665,257 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(665,257) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(665,257) x common factors =1 x 1 = 1
LCM(665,257) = ( 665 × 257 ) / 1
LCM(665,257) = 170905 / 1
LCM(665,257) = 170905
