1,2,3,4,6,9,12,18,36
Greatest Common Factor
We found the factors 68,93,71,36 . The biggest common factor number is the GCF number.
So the greatest common factor 68,93,71,36 is 1.
Lets's calculate LCM of 81,17,47,37
Given numbers has no common factors except 1. So, there LCM is their product i.e 2394603
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2394603
Therefore, the GCF of Fractions 68/81,93/17,71/47,36/37 is 1/2394603
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 81,17,47,37 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,17,47,37) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,17,47,37) x common factors =1 x 1 = 1
LCM(81,17,47,37) = ( 81 × 17 × 47 × 37 ) / 1
LCM(81,17,47,37) = 2394603 / 1
LCM(81,17,47,37) = 2394603
Here are some samples of GCF of Fractions calculations.
