Lets's calculate LCM of 80,2740
2 | 80, 2740 |
2 | 40, 1370 |
5 | 20, 685 |
4, 137 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 4 x 137 = 10960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/10960
Therefore, the GCF of Fractions 168/80,742/2740 is 14/10960
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 80,2740 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,2740) = 20
common factors(in case of two or more numbers have common factors) = 1
GCF(80,2740) x common factors =20 x 1 = 20
LCM(80,2740) = ( 80 × 2740 ) / 20
LCM(80,2740) = 219200 / 20
LCM(80,2740) = 10960
