Lets's calculate LCM of 169,822
Given numbers has no common factors except 1. So, there LCM is their product i.e 138918
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/138918
Therefore, the GCF of Fractions 378/169,4378/822 is 2/138918
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 169,822 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(169,822) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(169,822) x common factors =1 x 1 = 1
LCM(169,822) = ( 169 × 822 ) / 1
LCM(169,822) = 138918 / 1
LCM(169,822) = 138918
Here are some samples of GCF of Fractions calculations.
