Greatest Common Factor
We found the factors 25,605,221 . The biggest common factor number is the GCF number.
So the greatest common factor 25,605,221 is 1.
Lets's calculate LCM of 51,76,148
2 | 51, 76, 148 |
2 | 51, 38, 74 |
51, 19, 37 |
∴ So the LCM of the given numbers is 2 x 2 x 51 x 19 x 37 = 143412
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/143412
Therefore, the GCF of Fractions 25/51,605/76,221/148 is 1/143412
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 51,76,148 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,76,148) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(51,76,148) x common factors =1 x 4 = 4
LCM(51,76,148) = ( 51 × 76 × 148 ) / 4
LCM(51,76,148) = 573648 / 4
LCM(51,76,148) = 143412
