Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 213/20,894/156
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 213,894
Greatest Common Factor of Numerators i.e. GCF of 213,894 is 3 .
LCM of Denominators means LCM of 20,156 as per the given fractions.
LCM of 20,156 is 780 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 213,894
3 | 213, 894 |
71, 298 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 213
List of positive integer factors of 213 that divides 213 without a remainder.
1,3,71,213
Factors of 894
List of positive integer factors of 894 that divides 894 without a remainder.
1,2,3,6,149,298,447,894
Greatest Common Factor
We found the factors 213,894 . The biggest common factor number is the GCF number.
So the greatest common factor 213,894 is 3.
Lets's calculate LCM of 20,156
2 | 20, 156 |
2 | 10, 78 |
5, 39 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 39 = 780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/780
Therefore, the GCF of Fractions 213/20,894/156 is 3/780
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 20,156 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,156) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(20,156) x common factors =4 x 1 = 4
LCM(20,156) = ( 20 × 156 ) / 4
LCM(20,156) = 3120 / 4
LCM(20,156) = 780
