Greatest Common Factor
We found the factors 29,84,91,42 . The biggest common factor number is the GCF number.
So the greatest common factor 29,84,91,42 is 1.
Lets's calculate LCM of 55,44,66,397
2 | 55, 44, 66, 397 |
11 | 55, 22, 33, 397 |
5, 2, 3, 397 |
∴ So the LCM of the given numbers is 2 x 11 x 5 x 2 x 3 x 397 = 262020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/262020
Therefore, the GCF of Fractions 29/55,84/44,91/66,42/397 is 1/262020
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 55,44,66,397 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,44,66,397) = 1
common factors(in case of two or more numbers have common factors) = 242
GCF(55,44,66,397) x common factors =1 x 242 = 242
LCM(55,44,66,397) = ( 55 × 44 × 66 × 397 ) / 242
LCM(55,44,66,397) = 63408840 / 242
LCM(55,44,66,397) = 262020
