Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 128/60,123/175
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 128,123
Greatest Common Factor of Numerators i.e. GCF of 128,123 is 1 .
LCM of Denominators means LCM of 60,175 as per the given fractions.
LCM of 60,175 is 2100 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 128,123
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 128
List of positive integer factors of 128 that divides 128 without a remainder.
1,2,4,8,16,32,64,128
Factors of 123
List of positive integer factors of 123 that divides 123 without a remainder.
1,3,41,123
Greatest Common Factor
We found the factors 128,123 . The biggest common factor number is the GCF number.
So the greatest common factor 128,123 is 1.
Lets's calculate LCM of 60,175
5 | 60, 175 |
12, 35 |
∴ So the LCM of the given numbers is 5 x 12 x 35 = 2100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2100
Therefore, the GCF of Fractions 128/60,123/175 is 1/2100
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 60,175 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(60,175) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(60,175) x common factors =5 x 1 = 5
LCM(60,175) = ( 60 × 175 ) / 5
LCM(60,175) = 10500 / 5
LCM(60,175) = 2100
