Greatest Common Factor
We found the factors 45,63,126 . The biggest common factor number is the GCF number.
So the greatest common factor 45,63,126 is 9.
Lets's calculate LCM of 84,94,77
2 | 84, 94, 77 |
7 | 42, 47, 77 |
6, 47, 11 |
∴ So the LCM of the given numbers is 2 x 7 x 6 x 47 x 11 = 43428
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/43428
Therefore, the GCF of Fractions 45/84,63/94,126/77 is 9/43428
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 84,94,77 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,94,77) = 1
common factors(in case of two or more numbers have common factors) = 14
GCF(84,94,77) x common factors =1 x 14 = 14
LCM(84,94,77) = ( 84 × 94 × 77 ) / 14
LCM(84,94,77) = 607992 / 14
LCM(84,94,77) = 43428
