Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 141/42,470/840
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 141,470
Greatest Common Factor of Numerators i.e. GCF of 141,470 is 47 .
LCM of Denominators means LCM of 42,840 as per the given fractions.
LCM of 42,840 is 840 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 141,470
47 | 141, 470 |
3, 10 |
∴ So the GCF of the given numbers is 47 = 47
Factors of 141
List of positive integer factors of 141 that divides 141 without a remainder.
1,3,47,141
Factors of 470
List of positive integer factors of 470 that divides 470 without a remainder.
1,2,5,10,47,94,235,470
Greatest Common Factor
We found the factors 141,470 . The biggest common factor number is the GCF number.
So the greatest common factor 141,470 is 47.
Lets's calculate LCM of 42,840
2 | 42, 840 |
3 | 21, 420 |
7 | 7, 140 |
1, 20 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 20 = 840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 47/840
Therefore, the GCF of Fractions 141/42,470/840 is 47/840
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 42,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,840) = 42
common factors(in case of two or more numbers have common factors) = 1
GCF(42,840) x common factors =42 x 1 = 42
LCM(42,840) = ( 42 × 840 ) / 42
LCM(42,840) = 35280 / 42
LCM(42,840) = 840
