Greatest Common Factor
We found the factors 26,86,942 . The biggest common factor number is the GCF number.
So the greatest common factor 26,86,942 is 2.
Lets's calculate LCM of 84,21,86
2 | 84, 21, 86 |
3 | 42, 21, 43 |
7 | 14, 7, 43 |
2, 1, 43 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 2 x 1 x 43 = 3612
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/3612
Therefore, the GCF of Fractions 26/84,86/21,942/86 is 2/3612
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 84,21,86 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,21,86) = 1
common factors(in case of two or more numbers have common factors) = 42
GCF(84,21,86) x common factors =1 x 42 = 42
LCM(84,21,86) = ( 84 × 21 × 86 ) / 42
LCM(84,21,86) = 151704 / 42
LCM(84,21,86) = 3612
