So the greatest common factor 408,1555 is 1.
Lets's calculate LCM of 720,134
2 | 720, 134 |
360, 67 |
∴ So the LCM of the given numbers is 2 x 360 x 67 = 48240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/48240
Therefore, the GCF of Fractions 408/720,1555/134 is 1/48240
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 720,134 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(720,134) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(720,134) x common factors =2 x 1 = 2
LCM(720,134) = ( 720 × 134 ) / 2
LCM(720,134) = 96480 / 2
LCM(720,134) = 48240
