Greatest Common Factor
We found the factors 35,66,12,18 . The biggest common factor number is the GCF number.
So the greatest common factor 35,66,12,18 is 1.
Lets's calculate LCM of 78,44,30,300
2 | 78, 44, 30, 300 |
2 | 39, 22, 15, 150 |
3 | 39, 11, 15, 75 |
5 | 13, 11, 5, 25 |
13, 11, 1, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 13 x 11 x 1 x 5 = 42900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/42900
Therefore, the GCF of Fractions 35/78,66/44,12/30,18/300 is 1/42900
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 78,44,30,300 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,44,30,300) = 2
common factors(in case of two or more numbers have common factors) = 360
GCF(78,44,30,300) x common factors =2 x 360 = 720
LCM(78,44,30,300) = ( 78 × 44 × 30 × 300 ) / 720
LCM(78,44,30,300) = 30888000 / 720
LCM(78,44,30,300) = 42900
