Greatest Common Factor
We found the factors 63,42,58,81 . The biggest common factor number is the GCF number.
So the greatest common factor 63,42,58,81 is 1.
Lets's calculate LCM of 27,13,25,68
Given numbers has no common factors except 1. So, there LCM is their product i.e 596700
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/596700
Therefore, the GCF of Fractions 63/27,42/13,58/25,81/68 is 1/596700
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 27,13,25,68 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(27,13,25,68) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(27,13,25,68) x common factors =1 x 1 = 1
LCM(27,13,25,68) = ( 27 × 13 × 25 × 68 ) / 1
LCM(27,13,25,68) = 596700 / 1
LCM(27,13,25,68) = 596700
Here are some samples of GCF of Fractions calculations.
