We found the factors 98,69,20,45 . The biggest common factor number is the GCF number.
So the greatest common factor 98,69,20,45 is 1.
Lets's calculate LCM of 99,90,44,579
2 | 99, 90, 44, 579 |
3 | 99, 45, 22, 579 |
3 | 33, 15, 22, 193 |
11 | 11, 5, 22, 193 |
1, 5, 2, 193 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 11 x 1 x 5 x 2 x 193 = 382140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/382140
Therefore, the GCF of Fractions 98/99,69/90,20/44,45/579 is 1/382140
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 99,90,44,579 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,90,44,579) = 1
common factors(in case of two or more numbers have common factors) = 594
GCF(99,90,44,579) x common factors =1 x 594 = 594
LCM(99,90,44,579) = ( 99 × 90 × 44 × 579 ) / 594
LCM(99,90,44,579) = 226991160 / 594
LCM(99,90,44,579) = 382140
