Greatest Common Factor
We found the factors 18,318,914 . The biggest common factor number is the GCF number.
So the greatest common factor 18,318,914 is 2.
Lets's calculate LCM of 210,551,208
2 | 210, 551, 208 |
105, 551, 104 |
∴ So the LCM of the given numbers is 2 x 105 x 551 x 104 = 12033840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/12033840
Therefore, the GCF of Fractions 18/210,318/551,914/208 is 2/12033840
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 210,551,208 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(210,551,208) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(210,551,208) x common factors =1 x 2 = 2
LCM(210,551,208) = ( 210 × 551 × 208 ) / 2
LCM(210,551,208) = 24067680 / 2
LCM(210,551,208) = 12033840
