Lets's calculate LCM of 918,642
2 | 918, 642 |
3 | 459, 321 |
153, 107 |
∴ So the LCM of the given numbers is 2 x 3 x 153 x 107 = 98226
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/98226
Therefore, the GCF of Fractions 511/918,418/642 is 1/98226
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 918,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(918,642) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(918,642) x common factors =6 x 1 = 6
LCM(918,642) = ( 918 × 642 ) / 6
LCM(918,642) = 589356 / 6
LCM(918,642) = 98226
