Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 7/63,2/90,5/25,51/945
To find the GCF of fractions, we have to find the GCF of numerator numbers and LCM of denominator numbers. Its formula is given by
GCF of Fraction = Greatest Common Factor of Numerator/Least Common Multiple of Denominators
In the fractions 7/63,2/90,5/25,51/945, numerators are 7,2,5,51
Denominators are 63,90,25,945
The GCF of 7,2,5,51 is 1 .
LCM of 63,90,25,945 is 9450.
The greatest common factor of 7/63,2/90,5/25,51/945 = [GCF of 7,2,5,51]/[LCM of 63,90,25,945]= 1/9450

Greatest Common Factor
We found the factors 7,2,5,51 . The biggest common factor number is the GCF number.
So the greatest common factor 7,2,5,51 is 1.
Lets's calculate LCM of 63,90,25,945
3 | 63, 90, 25, 945 |
3 | 21, 30, 25, 315 |
5 | 7, 10, 25, 105 |
7 | 7, 2, 5, 21 |
1, 2, 5, 3 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 7 x 1 x 2 x 5 x 3 = 9450
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9450
Therefore, the GCF of Fractions 7/63,2/90,5/25,51/945 is 1/9450
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 63,90,25,945 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,90,25,945) = 1
common factors(in case of two or more numbers have common factors) = 14175
GCF(63,90,25,945) x common factors =1 x 14175 = 14175
LCM(63,90,25,945) = ( 63 × 90 × 25 × 945 ) / 14175
LCM(63,90,25,945) = 133953750 / 14175
LCM(63,90,25,945) = 9450
