1,3,5,9,15,17,45,51,85,153,255,765
Factors of 899
List of positive integer factors of 899 that divides 899 without a remainder.
1,29,31,899
Greatest Common Factor
We found the factors 459,765,899 . The biggest common factor number is the GCF number.
So the greatest common factor 459,765,899 is 1.
Lets's calculate LCM of 18,72,91
2 | 18, 72, 91 |
3 | 9, 36, 91 |
3 | 3, 12, 91 |
1, 4, 91 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 1 x 4 x 91 = 6552
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6552
Therefore, the GCF of Fractions 459/18,765/72,899/91 is 1/6552
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 18,72,91 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,72,91) = 1
common factors(in case of two or more numbers have common factors) = 18
GCF(18,72,91) x common factors =1 x 18 = 18
LCM(18,72,91) = ( 18 × 72 × 91 ) / 18
LCM(18,72,91) = 117936 / 18
LCM(18,72,91) = 6552
