Greatest Common Factor
We found the factors 18,38,76,625 . The biggest common factor number is the GCF number.
So the greatest common factor 18,38,76,625 is 1.
Lets's calculate LCM of 51,48,46,48
2 | 51, 48, 46, 48 |
2 | 51, 24, 23, 24 |
2 | 51, 12, 23, 12 |
2 | 51, 6, 23, 6 |
3 | 51, 3, 23, 3 |
17, 1, 23, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 17 x 1 x 23 x 1 = 18768
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18768
Therefore, the GCF of Fractions 18/51,38/48,76/46,625/48 is 1/18768
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 51,48,46,48 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,48,46,48) = 1
common factors(in case of two or more numbers have common factors) = 288
GCF(51,48,46,48) x common factors =1 x 288 = 288
LCM(51,48,46,48) = ( 51 × 48 × 46 × 48 ) / 288
LCM(51,48,46,48) = 5405184 / 288
LCM(51,48,46,48) = 18768
