1,71
Factors of 906
List of positive integer factors of 906 that divides 906 without a remainder.
1,2,3,6,151,302,453,906
Greatest Common Factor
We found the factors 49,96,71,906 . The biggest common factor number is the GCF number.
So the greatest common factor 49,96,71,906 is 1.
Lets's calculate LCM of 19,62,12,78
2 | 19, 62, 12, 78 |
3 | 19, 31, 6, 39 |
19, 31, 2, 13 |
∴ So the LCM of the given numbers is 2 x 3 x 19 x 31 x 2 x 13 = 91884
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/91884
Therefore, the GCF of Fractions 49/19,96/62,71/12,906/78 is 1/91884
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 19,62,12,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,62,12,78) = 1
common factors(in case of two or more numbers have common factors) = 12
GCF(19,62,12,78) x common factors =1 x 12 = 12
LCM(19,62,12,78) = ( 19 × 62 × 12 × 78 ) / 12
LCM(19,62,12,78) = 1102608 / 12
LCM(19,62,12,78) = 91884
