Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 72/890,96/2638
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 72,96
Greatest Common Factor of Numerators i.e. GCF of 72,96 is 24 .
LCM of Denominators means LCM of 890,2638 as per the given fractions.
LCM of 890,2638 is 1173910 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 72,96
2 | 72, 96 |
2 | 36, 48 |
2 | 18, 24 |
3 | 9, 12 |
3, 4 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 3 = 24

List of positive integer factors of 72 that divides 72 without a remainder.
1,2,3,4,6,8,9,12,18,24,36,72
Factors of 96
List of positive integer factors of 96 that divides 96 without a remainder.
1,2,3,4,6,8,12,16,24,32,48,96
Greatest Common Factor
We found the factors 72,96 . The biggest common factor number is the GCF number.
So the greatest common factor 72,96 is 24.
Lets's calculate LCM of 890,2638
2 | 890, 2638 |
445, 1319 |
∴ So the LCM of the given numbers is 2 x 445 x 1319 = 1173910
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 24/1173910
Therefore, the GCF of Fractions 72/890,96/2638 is 24/1173910
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 890,2638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(890,2638) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(890,2638) x common factors =2 x 1 = 2
LCM(890,2638) = ( 890 × 2638 ) / 2
LCM(890,2638) = 2347820 / 2
LCM(890,2638) = 1173910
