Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 612/174,248/870
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 612,248
Greatest Common Factor of Numerators i.e. GCF of 612,248 is 4 .
LCM of Denominators means LCM of 174,870 as per the given fractions.
LCM of 174,870 is 870 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 612,248
2 | 612, 248 |
2 | 306, 124 |
153, 62 |
∴ So the GCF of the given numbers is 2 x 2 = 4

Factors of 248
List of positive integer factors of 248 that divides 248 without a remainder.
1,2,4,8,31,62,124,248
Greatest Common Factor
We found the factors 612,248 . The biggest common factor number is the GCF number.
So the greatest common factor 612,248 is 4.
Lets's calculate LCM of 174,870
2 | 174, 870 |
3 | 87, 435 |
29 | 29, 145 |
1, 5 |
∴ So the LCM of the given numbers is 2 x 3 x 29 x 1 x 5 = 870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/870
Therefore, the GCF of Fractions 612/174,248/870 is 4/870
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 174,870 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(174,870) = 174
common factors(in case of two or more numbers have common factors) = 1
GCF(174,870) x common factors =174 x 1 = 174
LCM(174,870) = ( 174 × 870 ) / 174
LCM(174,870) = 151380 / 174
LCM(174,870) = 870
