1,2,23,46
Greatest Common Factor
We found the factors 21,25,98,46 . The biggest common factor number is the GCF number.
So the greatest common factor 21,25,98,46 is 1.
Lets's calculate LCM of 60,32,17,906
2 | 60, 32, 17, 906 |
2 | 30, 16, 17, 453 |
3 | 15, 8, 17, 453 |
5, 8, 17, 151 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 8 x 17 x 151 = 1232160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1232160
Therefore, the GCF of Fractions 21/60,25/32,98/17,46/906 is 1/1232160
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 60,32,17,906 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(60,32,17,906) = 1
common factors(in case of two or more numbers have common factors) = 24
GCF(60,32,17,906) x common factors =1 x 24 = 24
LCM(60,32,17,906) = ( 60 × 32 × 17 × 906 ) / 24
LCM(60,32,17,906) = 29571840 / 24
LCM(60,32,17,906) = 1232160
