1,3,9,11,33,99
Factors of 93
List of positive integer factors of 93 that divides 93 without a remainder.
1,3,31,93
Greatest Common Factor
We found the factors 81,37,99,93 . The biggest common factor number is the GCF number.
So the greatest common factor 81,37,99,93 is 1.
Lets's calculate LCM of 84,20,18,52
2 | 84, 20, 18, 52 |
2 | 42, 10, 9, 26 |
3 | 21, 5, 9, 13 |
7, 5, 3, 13 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 5 x 3 x 13 = 16380
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/16380
Therefore, the GCF of Fractions 81/84,37/20,99/18,93/52 is 1/16380
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 84,20,18,52 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,20,18,52) = 2
common factors(in case of two or more numbers have common factors) = 48
GCF(84,20,18,52) x common factors =2 x 48 = 96
LCM(84,20,18,52) = ( 84 × 20 × 18 × 52 ) / 96
LCM(84,20,18,52) = 1572480 / 96
LCM(84,20,18,52) = 16380
