What is the GCF of 5/40,7/75,2/60,77/730?
Given fractions are 5/40,7/75,2/60,77/730
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 5/40,7/75,2/60,77/730, numerators are 5,7,2,77
Denominators are 40,75,60,730
The GCF of 5,7,2,77 is 1 .
LCM of 40,75,60,730 is 43800.
The greatest common factor of 5/40,7/75,2/60,77/730 = [GCF of 5,7,2,77]/[LCM of 40,75,60,730]= 1/43800
Therefore, the GCF of 5/40,7/75,2/60,77/730 is 1/43800.

Lets's calculate LCM of 40,75,60,730
| 2 | 40, 75, 60, 730 |
| 2 | 20, 75, 30, 365 |
| 3 | 10, 75, 15, 365 |
| 5 | 10, 25, 5, 365 |
| 2, 1, 5, 73 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 2 x 1 x 5 x 73 = 43800
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/43800

Least Common Multiple of 40,75,60,730 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 40,75,60,730 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,75,60,730) = 5
common factors(in case of two or more numbers have common factors) = 600
GCF(40,75,60,730) x common factors =5 x 600 = 3000
LCM(40,75,60,730) = ( 40 × 75 × 60 × 730 ) / 3000
LCM(40,75,60,730) = 131400000 / 3000
LCM(40,75,60,730) = 43800
