So the greatest common factor 69,96,162 is 3.
Lets's calculate LCM of 72,86,90
2 | 72, 86, 90 |
3 | 36, 43, 45 |
3 | 12, 43, 15 |
4, 43, 5 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 4 x 43 x 5 = 15480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/15480
Therefore, the GCF of Fractions 69/72,96/86,162/90 is 3/15480
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 72,86,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,86,90) = 2
common factors(in case of two or more numbers have common factors) = 18
GCF(72,86,90) x common factors =2 x 18 = 36
LCM(72,86,90) = ( 72 × 86 × 90 ) / 36
LCM(72,86,90) = 557280 / 36
LCM(72,86,90) = 15480
