Lets's calculate LCM of 646,332
2 | 646, 332 |
323, 166 |
∴ So the LCM of the given numbers is 2 x 323 x 166 = 107236
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/107236
Therefore, the GCF of Fractions 693/646,245/332 is 7/107236
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 646,332 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(646,332) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(646,332) x common factors =2 x 1 = 2
LCM(646,332) = ( 646 × 332 ) / 2
LCM(646,332) = 214472 / 2
LCM(646,332) = 107236
