We found the factors 147,3216 . The biggest common factor number is the GCF number.
So the greatest common factor 147,3216 is 3.
Lets's calculate LCM of 351,290
Given numbers has no common factors except 1. So, there LCM is their product i.e 101790
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/101790
Therefore, the GCF of Fractions 147/351,3216/290 is 3/101790
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 351,290 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(351,290) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(351,290) x common factors =1 x 1 = 1
LCM(351,290) = ( 351 × 290 ) / 1
LCM(351,290) = 101790 / 1
LCM(351,290) = 101790
Here are some samples of GCF of Fractions calculations.
