What is the GCF of 82/40,31/34,42/95,13/52?
Given fractions are 82/40,31/34,42/95,13/52
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 82/40,31/34,42/95,13/52, numerators are 82,31,42,13
Denominators are 40,34,95,52
The GCF of 82,31,42,13 is 1 .
LCM of 40,34,95,52 is 167960.
The greatest common factor of 82/40,31/34,42/95,13/52 = [GCF of 82,31,42,13]/[LCM of 40,34,95,52]= 1/167960
Therefore, the GCF of 82/40,31/34,42/95,13/52 is 1/167960.

Greatest Common Factor
We found the factors 82,31,42,13 . The biggest common factor number is the GCF number.
So the greatest common factor 82,31,42,13 is 1.
Lets's calculate LCM of 40,34,95,52
| 2 | 40, 34, 95, 52 |
| 2 | 20, 17, 95, 26 |
| 5 | 10, 17, 95, 13 |
| 2, 17, 19, 13 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 2 x 17 x 19 x 13 = 167960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/167960
Therefore, the GCF of Fractions 82/40,31/34,42/95,13/52 is 1/167960
Least Common Multiple of 40,34,95,52 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 40,34,95,52 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,34,95,52) = 1
common factors(in case of two or more numbers have common factors) = 40
GCF(40,34,95,52) x common factors =1 x 40 = 40
LCM(40,34,95,52) = ( 40 × 34 × 95 × 52 ) / 40
LCM(40,34,95,52) = 6718400 / 40
LCM(40,34,95,52) = 167960
