Greatest Common Factor
We found the factors 23,420,719 . The biggest common factor number is the GCF number.
So the greatest common factor 23,420,719 is 1.
Lets's calculate LCM of 212,554,213
2 | 212, 554, 213 |
106, 277, 213 |
∴ So the LCM of the given numbers is 2 x 106 x 277 x 213 = 12508212
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12508212
Therefore, the GCF of Fractions 23/212,420/554,719/213 is 1/12508212
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 212,554,213 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(212,554,213) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(212,554,213) x common factors =1 x 2 = 2
LCM(212,554,213) = ( 212 × 554 × 213 ) / 2
LCM(212,554,213) = 25016424 / 2
LCM(212,554,213) = 12508212
