Greatest Common Factor
We found the factors 47,91,66,21 . The biggest common factor number is the GCF number.
So the greatest common factor 47,91,66,21 is 1.
Lets's calculate LCM of 94,24,66,923
2 | 94, 24, 66, 923 |
3 | 47, 12, 33, 923 |
47, 4, 11, 923 |
∴ So the LCM of the given numbers is 2 x 3 x 47 x 4 x 11 x 923 = 11452584
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11452584
Therefore, the GCF of Fractions 47/94,91/24,66/66,21/923 is 1/11452584
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 94,24,66,923 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(94,24,66,923) = 1
common factors(in case of two or more numbers have common factors) = 12
GCF(94,24,66,923) x common factors =1 x 12 = 12
LCM(94,24,66,923) = ( 94 × 24 × 66 × 923 ) / 12
LCM(94,24,66,923) = 137431008 / 12
LCM(94,24,66,923) = 11452584
