Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 915/78,479/740
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 915,479
Greatest Common Factor of Numerators i.e. GCF of 915,479 is 1 .
LCM of Denominators means LCM of 78,740 as per the given fractions.
LCM of 78,740 is 28860 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 915,479
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 915
List of positive integer factors of 915 that divides 915 without a remainder.
1,3,5,15,61,183,305,915
Factors of 479
List of positive integer factors of 479 that divides 479 without a remainder.
1,479
Greatest Common Factor
We found the factors 915,479 . The biggest common factor number is the GCF number.
So the greatest common factor 915,479 is 1.
Lets's calculate LCM of 78,740
2 | 78, 740 |
39, 370 |
∴ So the LCM of the given numbers is 2 x 39 x 370 = 28860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28860
Therefore, the GCF of Fractions 915/78,479/740 is 1/28860
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 78,740 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,740) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(78,740) x common factors =2 x 1 = 2
LCM(78,740) = ( 78 × 740 ) / 2
LCM(78,740) = 57720 / 2
LCM(78,740) = 28860
