Lets's calculate LCM of 798,266
2 | 798, 266 |
7 | 399, 133 |
19 | 57, 19 |
3, 1 |
∴ So the LCM of the given numbers is 2 x 7 x 19 x 3 x 1 = 798
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 16/798
Therefore, the GCF of Fractions 688/798,336/266 is 16/798
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 798,266 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(798,266) = 266
common factors(in case of two or more numbers have common factors) = 1
GCF(798,266) x common factors =266 x 1 = 266
LCM(798,266) = ( 798 × 266 ) / 266
LCM(798,266) = 212268 / 266
LCM(798,266) = 798
