Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 6/72,98/63,25/86,29/99
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 6,98,25,29
Greatest Common Factor of Numerators i.e. GCF of 6,98,25,29 is 1 .
LCM of Denominators means LCM of 72,63,86,99 as per the given fractions.
LCM of 72,63,86,99 is 238392 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 6,98,25,29
∴ So GCF of numbers is 1 because of no common factors present between them.

Factors of 29
List of positive integer factors of 29 that divides 29 without a remainder.
1,29
Greatest Common Factor
We found the factors 6,98,25,29 . The biggest common factor number is the GCF number.
So the greatest common factor 6,98,25,29 is 1.
Lets's calculate LCM of 72,63,86,99
2 | 72, 63, 86, 99 |
3 | 36, 63, 43, 99 |
3 | 12, 21, 43, 33 |
4, 7, 43, 11 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 4 x 7 x 43 x 11 = 238392
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/238392
Therefore, the GCF of Fractions 6/72,98/63,25/86,29/99 is 1/238392
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 72,63,86,99 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,63,86,99) = 1
common factors(in case of two or more numbers have common factors) = 162
GCF(72,63,86,99) x common factors =1 x 162 = 162
LCM(72,63,86,99) = ( 72 × 63 × 86 × 99 ) / 162
LCM(72,63,86,99) = 38619504 / 162
LCM(72,63,86,99) = 238392
