Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 24/63,31/84,42/54,73/136
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 24,31,42,73
Greatest Common Factor of Numerators i.e. GCF of 24,31,42,73 is 1 .
LCM of Denominators means LCM of 63,84,54,136 as per the given fractions.
LCM of 63,84,54,136 is 25704 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 24,31,42,73
∴ So GCF of numbers is 1 because of no common factors present between them.

Greatest Common Factor
We found the factors 24,31,42,73 . The biggest common factor number is the GCF number.
So the greatest common factor 24,31,42,73 is 1.
Lets's calculate LCM of 63,84,54,136
2 | 63, 84, 54, 136 |
2 | 63, 42, 27, 68 |
3 | 63, 21, 27, 34 |
3 | 7, 21, 9, 34 |
7 | 7, 7, 3, 34 |
1, 1, 3, 34 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 7 x 1 x 1 x 3 x 34 = 25704
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25704
Therefore, the GCF of Fractions 24/63,31/84,42/54,73/136 is 1/25704
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 63,84,54,136 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,84,54,136) = 1
common factors(in case of two or more numbers have common factors) = 1512
GCF(63,84,54,136) x common factors =1 x 1512 = 1512
LCM(63,84,54,136) = ( 63 × 84 × 54 × 136 ) / 1512
LCM(63,84,54,136) = 38864448 / 1512
LCM(63,84,54,136) = 25704
