Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 471/18,390/124
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 471,390
Greatest Common Factor of Numerators i.e. GCF of 471,390 is 3 .
LCM of Denominators means LCM of 18,124 as per the given fractions.
LCM of 18,124 is 1116 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 471,390
3 | 471, 390 |
157, 130 |
∴ So the GCF of the given numbers is 3 = 3

1,2,3,5,6,10,13,15,26,30,39,65,78,130,195,390
Greatest Common Factor
We found the factors 471,390 . The biggest common factor number is the GCF number.
So the greatest common factor 471,390 is 3.
Lets's calculate LCM of 18,124
2 | 18, 124 |
9, 62 |
∴ So the LCM of the given numbers is 2 x 9 x 62 = 1116
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1116
Therefore, the GCF of Fractions 471/18,390/124 is 3/1116
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 18,124 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,124) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(18,124) x common factors =2 x 1 = 2
LCM(18,124) = ( 18 × 124 ) / 2
LCM(18,124) = 2232 / 2
LCM(18,124) = 1116
