Lets's calculate LCM of 84,300
2 | 84, 300 |
2 | 42, 150 |
3 | 21, 75 |
7, 25 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 25 = 2100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/2100
Therefore, the GCF of Fractions 7240/84,6684/300 is 4/2100
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 84,300 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,300) = 12
common factors(in case of two or more numbers have common factors) = 1
GCF(84,300) x common factors =12 x 1 = 12
LCM(84,300) = ( 84 × 300 ) / 12
LCM(84,300) = 25200 / 12
LCM(84,300) = 2100
