Lets's calculate LCM of 11,86,20
2 | 11, 86, 20 |
11, 43, 10 |
∴ So the LCM of the given numbers is 2 x 11 x 43 x 10 = 9460
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/9460
Therefore, the GCF of Fractions 648/11,836/86,740/20 is 4/9460
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 11,86,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(11,86,20) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(11,86,20) x common factors =1 x 2 = 2
LCM(11,86,20) = ( 11 × 86 × 20 ) / 2
LCM(11,86,20) = 18920 / 2
LCM(11,86,20) = 9460
