Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 4/858,8/973
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 4,8
Greatest Common Factor of Numerators i.e. GCF of 4,8 is 4 .
LCM of Denominators means LCM of 858,973 as per the given fractions.
LCM of 858,973 is 834834 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 4,8
2 | 4, 8 |
2 | 2, 4 |
1, 2 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Factors of 4
List of positive integer factors of 4 that divides 4 without a remainder.
1,2,4
Factors of 8
List of positive integer factors of 8 that divides 8 without a remainder.
1,2,4,8
Greatest Common Factor
We found the factors 4,8 . The biggest common factor number is the GCF number.
So the greatest common factor 4,8 is 4.
Lets's calculate LCM of 858,973
Given numbers has no common factors except 1. So, there LCM is their product i.e 834834
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/834834
Therefore, the GCF of Fractions 4/858,8/973 is 4/834834
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 858,973 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(858,973) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(858,973) x common factors =1 x 1 = 1
LCM(858,973) = ( 858 × 973 ) / 1
LCM(858,973) = 834834 / 1
LCM(858,973) = 834834
