So the greatest common factor 948,424 is 4.
Lets's calculate LCM of 256,670
2 | 256, 670 |
128, 335 |
∴ So the LCM of the given numbers is 2 x 128 x 335 = 85760
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/85760
Therefore, the GCF of Fractions 948/256,424/670 is 4/85760
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 256,670 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(256,670) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(256,670) x common factors =2 x 1 = 2
LCM(256,670) = ( 256 × 670 ) / 2
LCM(256,670) = 171520 / 2
LCM(256,670) = 85760
