1,3,9,11,33,99
Factors of 10
List of positive integer factors of 10 that divides 10 without a remainder.
1,2,5,10
Factors of 12
List of positive integer factors of 12 that divides 12 without a remainder.
1,2,3,4,6,12
Greatest Common Factor
We found the factors 18,99,10,12 . The biggest common factor number is the GCF number.
So the greatest common factor 18,99,10,12 is 1.
Lets's calculate LCM of 90,62,32,916
2 | 90, 62, 32, 916 |
2 | 45, 31, 16, 458 |
45, 31, 8, 229 |
∴ So the LCM of the given numbers is 2 x 2 x 45 x 31 x 8 x 229 = 10222560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10222560
Therefore, the GCF of Fractions 18/90,99/62,10/32,12/916 is 1/10222560
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 90,62,32,916 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,62,32,916) = 2
common factors(in case of two or more numbers have common factors) = 8
GCF(90,62,32,916) x common factors =2 x 8 = 16
LCM(90,62,32,916) = ( 90 × 62 × 32 × 916 ) / 16
LCM(90,62,32,916) = 163560960 / 16
LCM(90,62,32,916) = 10222560
