Factors of 147
List of positive integer factors of 147 that divides 147 without a remainder.
1,3,7,21,49,147
Greatest Common Factor
We found the factors 980,147 . The biggest common factor number is the GCF number.
So the greatest common factor 980,147 is 49.
Lets's calculate LCM of 735,747
3 | 735, 747 |
245, 249 |
∴ So the LCM of the given numbers is 3 x 245 x 249 = 183015
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 49/183015
Therefore, the GCF of Fractions 980/735,147/747 is 49/183015
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 735,747 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(735,747) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(735,747) x common factors =3 x 1 = 3
LCM(735,747) = ( 735 × 747 ) / 3
LCM(735,747) = 549045 / 3
LCM(735,747) = 183015
