Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 25/77,19/45,213/585
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 25,19,213
Greatest Common Factor of Numerators i.e. GCF of 25,19,213 is 1 .
LCM of Denominators means LCM of 77,45,585 as per the given fractions.
LCM of 77,45,585 is 45045 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 25,19,213
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 25
List of positive integer factors of 25 that divides 25 without a remainder.
1,5,25
Factors of 19
List of positive integer factors of 19 that divides 19 without a remainder.
1,19
Factors of 213
List of positive integer factors of 213 that divides 213 without a remainder.
1,3,71,213
Greatest Common Factor
We found the factors 25,19,213 . The biggest common factor number is the GCF number.
So the greatest common factor 25,19,213 is 1.
Lets's calculate LCM of 77,45,585
3 | 77, 45, 585 |
3 | 77, 15, 195 |
5 | 77, 5, 65 |
77, 1, 13 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 77 x 1 x 13 = 45045
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/45045
Therefore, the GCF of Fractions 25/77,19/45,213/585 is 1/45045
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 77,45,585 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,45,585) = 1
common factors(in case of two or more numbers have common factors) = 45
GCF(77,45,585) x common factors =1 x 45 = 45
LCM(77,45,585) = ( 77 × 45 × 585 ) / 45
LCM(77,45,585) = 2027025 / 45
LCM(77,45,585) = 45045
