What is the GCF of 40/15,42/24,601/45?
Given fractions are 40/15,42/24,601/45
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 40/15,42/24,601/45, numerators are 40,42,601
Denominators are 15,24,45
The GCF of 40,42,601 is 1 .
LCM of 15,24,45 is 360.
The greatest common factor of 40/15,42/24,601/45 = [GCF of 40,42,601]/[LCM of 15,24,45]= 1/360
Therefore, the GCF of 40/15,42/24,601/45 is 1/360.
To find the highest common factor of 40,42,601, we have to find the factors of both numbers and list the highest common factor.
The factors of 40 are 1, 2, 4, 5, 8, 10, 20, 40
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42
The factors of 601 are 1, 601
The HCF of 40,42,601 is 1.
Lets's calculate GCF of 40,42,601
∴ So GCF of numbers is 1 because of no common factors present between them.
Greatest Common Factor of 40,42,601 By Matching Biggest Common Factor Method
Now, list down the factors of 40
:1,2,4,5,8,10,20,40

So the greatest common factor 40,42,601 is 1.
Lets's calculate LCM of 15,24,45
| 3 | 15, 24, 45 |
| 5 | 5, 8, 15 |
| 1, 8, 3 |
∴ So the LCM of the given numbers is 3 x 5 x 1 x 8 x 3 = 360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/360
Therefore, the GCF of Fractions 40/15,42/24,601/45 is 1/360
Least Common Multiple of 15,24,45 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 15,24,45 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,24,45) = 3
common factors(in case of two or more numbers have common factors) = 15
GCF(15,24,45) x common factors =3 x 15 = 45
LCM(15,24,45) = ( 15 × 24 × 45 ) / 45
LCM(15,24,45) = 16200 / 45
LCM(15,24,45) = 360
