1,2,4,5,8,10,20,25,29,40,50,58,100,116,145,200,232,290,580,725,1160,1450,2900,5800
Greatest Common Factor
We found the factors 540,5800 . The biggest common factor number is the GCF number.
So the greatest common factor 540,5800 is 20.
Lets's calculate LCM of 640,275
5 | 640, 275 |
128, 55 |
∴ So the LCM of the given numbers is 5 x 128 x 55 = 35200
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/35200
Therefore, the GCF of Fractions 540/640,5800/275 is 20/35200
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 640,275 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(640,275) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(640,275) x common factors =5 x 1 = 5
LCM(640,275) = ( 640 × 275 ) / 5
LCM(640,275) = 176000 / 5
LCM(640,275) = 35200
