Lets's calculate LCM of 442,7420
2 | 442, 7420 |
221, 3710 |
∴ So the LCM of the given numbers is 2 x 221 x 3710 = 1639820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/1639820
Therefore, the GCF of Fractions 2151/442,1098/7420 is 9/1639820
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 442,7420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(442,7420) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(442,7420) x common factors =2 x 1 = 2
LCM(442,7420) = ( 442 × 7420 ) / 2
LCM(442,7420) = 3279640 / 2
LCM(442,7420) = 1639820
