Lets's calculate LCM of 486,228
2 | 486, 228 |
3 | 243, 114 |
81, 38 |
∴ So the LCM of the given numbers is 2 x 3 x 81 x 38 = 18468
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/18468
Therefore, the GCF of Fractions 7857/486,5484/228 is 3/18468
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 486,228 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(486,228) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(486,228) x common factors =6 x 1 = 6
LCM(486,228) = ( 486 × 228 ) / 6
LCM(486,228) = 110808 / 6
LCM(486,228) = 18468
