1,3,5,9,15,45
Greatest Common Factor
We found the factors 23,99,19,45 . The biggest common factor number is the GCF number.
So the greatest common factor 23,99,19,45 is 1.
Lets's calculate LCM of 30,94,57,258
2 | 30, 94, 57, 258 |
3 | 15, 47, 57, 129 |
5, 47, 19, 43 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 47 x 19 x 43 = 1151970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1151970
Therefore, the GCF of Fractions 23/30,99/94,19/57,45/258 is 1/1151970
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 30,94,57,258 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,94,57,258) = 1
common factors(in case of two or more numbers have common factors) = 36
GCF(30,94,57,258) x common factors =1 x 36 = 36
LCM(30,94,57,258) = ( 30 × 94 × 57 × 258 ) / 36
LCM(30,94,57,258) = 41470920 / 36
LCM(30,94,57,258) = 1151970
