Lets's calculate LCM of 86,28,468
2 | 86, 28, 468 |
2 | 43, 14, 234 |
43, 7, 117 |
∴ So the LCM of the given numbers is 2 x 2 x 43 x 7 x 117 = 140868
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/140868
Therefore, the GCF of Fractions 68/86,360/28,406/468 is 2/140868
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 86,28,468 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,28,468) = 2
common factors(in case of two or more numbers have common factors) = 4
GCF(86,28,468) x common factors =2 x 4 = 8
LCM(86,28,468) = ( 86 × 28 × 468 ) / 8
LCM(86,28,468) = 1126944 / 8
LCM(86,28,468) = 140868
