Lets's calculate LCM of 392,840
2 | 392, 840 |
2 | 196, 420 |
2 | 98, 210 |
7 | 49, 105 |
7, 15 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 7 x 15 = 5880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5880
Therefore, the GCF of Fractions 595/392,678/840 is 1/5880
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 392,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(392,840) = 56
common factors(in case of two or more numbers have common factors) = 1
GCF(392,840) x common factors =56 x 1 = 56
LCM(392,840) = ( 392 × 840 ) / 56
LCM(392,840) = 329280 / 56
LCM(392,840) = 5880
