Greatest Common Factor
We found the factors 97,53,79,91 . The biggest common factor number is the GCF number.
So the greatest common factor 97,53,79,91 is 1.
Lets's calculate LCM of 84,75,44,60
2 | 84, 75, 44, 60 |
2 | 42, 75, 22, 30 |
3 | 21, 75, 11, 15 |
5 | 7, 25, 11, 5 |
7, 1, 11, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 7 x 1 x 11 x 5 = 23100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/23100
Therefore, the GCF of Fractions 97/84,53/75,79/44,91/60 is 1/23100
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 84,75,44,60 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,75,44,60) = 1
common factors(in case of two or more numbers have common factors) = 720
GCF(84,75,44,60) x common factors =1 x 720 = 720
LCM(84,75,44,60) = ( 84 × 75 × 44 × 60 ) / 720
LCM(84,75,44,60) = 16632000 / 720
LCM(84,75,44,60) = 23100
