Lets's calculate LCM of 312,468
2 | 312, 468 |
2 | 156, 234 |
3 | 78, 117 |
13 | 26, 39 |
2, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 13 x 2 x 3 = 936
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/936
Therefore, the GCF of Fractions 820/312,192/468 is 4/936
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 312,468 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(312,468) = 156
common factors(in case of two or more numbers have common factors) = 1
GCF(312,468) x common factors =156 x 1 = 156
LCM(312,468) = ( 312 × 468 ) / 156
LCM(312,468) = 146016 / 156
LCM(312,468) = 936
