Greatest Common Factor
We found the factors 105,8085 . The biggest common factor number is the GCF number.
So the greatest common factor 105,8085 is 105.
Lets's calculate LCM of 20,948
2 | 20, 948 |
2 | 10, 474 |
5, 237 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 237 = 4740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 105/4740
Therefore, the GCF of Fractions 105/20,8085/948 is 105/4740
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 20,948 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,948) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(20,948) x common factors =4 x 1 = 4
LCM(20,948) = ( 20 × 948 ) / 4
LCM(20,948) = 18960 / 4
LCM(20,948) = 4740
