Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 423/143,297/670
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 423,297
Greatest Common Factor of Numerators i.e. GCF of 423,297 is 9 .
LCM of Denominators means LCM of 143,670 as per the given fractions.
LCM of 143,670 is 95810 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 423,297
3 | 423, 297 |
3 | 141, 99 |
47, 33 |
∴ So the GCF of the given numbers is 3 x 3 = 9

1,3,9,47,141,423
Factors of 297
List of positive integer factors of 297 that divides 297 without a remainder.
1,3,9,11,27,33,99,297
Greatest Common Factor
We found the factors 423,297 . The biggest common factor number is the GCF number.
So the greatest common factor 423,297 is 9.
Lets's calculate LCM of 143,670
Given numbers has no common factors except 1. So, there LCM is their product i.e 95810
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/95810
Therefore, the GCF of Fractions 423/143,297/670 is 9/95810
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 143,670 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(143,670) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(143,670) x common factors =1 x 1 = 1
LCM(143,670) = ( 143 × 670 ) / 1
LCM(143,670) = 95810 / 1
LCM(143,670) = 95810
