What is the GCF of 23/15,24/20,25/24,120/48?
Given fractions are 23/15,24/20,25/24,120/48
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 23/15,24/20,25/24,120/48, numerators are 23,24,25,120
Denominators are 15,20,24,48
The GCF of 23,24,25,120 is 1 .
LCM of 15,20,24,48 is 240.
The greatest common factor of 23/15,24/20,25/24,120/48 = [GCF of 23,24,25,120]/[LCM of 15,20,24,48]= 1/240
Therefore, the GCF of 23/15,24/20,25/24,120/48 is 1/240.

Lets's calculate LCM of 15,20,24,48
| 2 | 15, 20, 24, 48 |
| 2 | 15, 10, 12, 24 |
| 2 | 15, 5, 6, 12 |
| 3 | 15, 5, 3, 6 |
| 5 | 5, 5, 1, 2 |
| 1, 1, 1, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 5 x 1 x 1 x 1 x 2 = 240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/240
Therefore, the GCF of Fractions 23/15,24/20,25/24,120/48 is 1/240
Least Common Multiple of 15,20,24,48 with GCF Formula
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 15,20,24,48 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,20,24,48) = 1
common factors(in case of two or more numbers have common factors) = 1440
GCF(15,20,24,48) x common factors =1 x 1440 = 1440
LCM(15,20,24,48) = ( 15 × 20 × 24 × 48 ) / 1440
LCM(15,20,24,48) = 345600 / 1440
LCM(15,20,24,48) = 240
