Greatest Common Factor
We found the factors 27,15,120 . The biggest common factor number is the GCF number.
So the greatest common factor 27,15,120 is 3.
Lets's calculate LCM of 437,685,230
5 | 437, 685, 230 |
23 | 437, 137, 46 |
19, 137, 2 |
∴ So the LCM of the given numbers is 5 x 23 x 19 x 137 x 2 = 598690
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/598690
Therefore, the GCF of Fractions 27/437,15/685,120/230 is 3/598690
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 437,685,230 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(437,685,230) = 1
common factors(in case of two or more numbers have common factors) = 115
GCF(437,685,230) x common factors =1 x 115 = 115
LCM(437,685,230) = ( 437 × 685 × 230 ) / 115
LCM(437,685,230) = 68849350 / 115
LCM(437,685,230) = 598690
