So the greatest common factor 2,438,654 is 2.
Lets's calculate LCM of 87,22,45
3 | 87, 22, 45 |
29, 22, 15 |
∴ So the LCM of the given numbers is 3 x 29 x 22 x 15 = 28710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/28710
Therefore, the GCF of Fractions 2/87,438/22,654/45 is 2/28710
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 87,22,45 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(87,22,45) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(87,22,45) x common factors =1 x 3 = 3
LCM(87,22,45) = ( 87 × 22 × 45 ) / 3
LCM(87,22,45) = 86130 / 3
LCM(87,22,45) = 28710
