:1,2,3,4,5,6,9,10,12,15,18,20,25,27,30,36,45,50,54,60,75,81,90,100,108,135,150,162,180,225,270,300,324,405,450,540,675,810,900,1350,1620,2025,2700,4050,8100
Greatest Common Factor
We found the factors 168,8100 . The biggest common factor number is the GCF number.
So the greatest common factor 168,8100 is 12.
Lets's calculate LCM of 570,385
5 | 570, 385 |
114, 77 |
∴ So the LCM of the given numbers is 5 x 114 x 77 = 43890
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/43890
Therefore, the GCF of Fractions 168/570,8100/385 is 12/43890
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 570,385 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(570,385) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(570,385) x common factors =5 x 1 = 5
LCM(570,385) = ( 570 × 385 ) / 5
LCM(570,385) = 219450 / 5
LCM(570,385) = 43890
