Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 156/249,372/385
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 156,372
Greatest Common Factor of Numerators i.e. GCF of 156,372 is 12 .
LCM of Denominators means LCM of 249,385 as per the given fractions.
LCM of 249,385 is 95865 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 156,372
2 | 156, 372 |
2 | 78, 186 |
3 | 39, 93 |
13, 31 |
∴ So the GCF of the given numbers is 2 x 2 x 3 = 12

1,2,3,4,6,12,31,62,93,124,186,372
Greatest Common Factor
We found the factors 156,372 . The biggest common factor number is the GCF number.
So the greatest common factor 156,372 is 12.
Lets's calculate LCM of 249,385
Given numbers has no common factors except 1. So, there LCM is their product i.e 95865
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/95865
Therefore, the GCF of Fractions 156/249,372/385 is 12/95865
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 249,385 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(249,385) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(249,385) x common factors =1 x 1 = 1
LCM(249,385) = ( 249 × 385 ) / 1
LCM(249,385) = 95865 / 1
LCM(249,385) = 95865
