We found the factors 860,260,245 . The biggest common factor number is the GCF number.
So the greatest common factor 860,260,245 is 5.
Lets's calculate LCM of 46,42,23
2 | 46, 42, 23 |
23 | 23, 21, 23 |
1, 21, 1 |
∴ So the LCM of the given numbers is 2 x 23 x 1 x 21 x 1 = 966
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/966
Therefore, the GCF of Fractions 860/46,260/42,245/23 is 5/966
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 46,42,23 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(46,42,23) = 1
common factors(in case of two or more numbers have common factors) = 46
GCF(46,42,23) x common factors =1 x 46 = 46
LCM(46,42,23) = ( 46 × 42 × 23 ) / 46
LCM(46,42,23) = 44436 / 46
LCM(46,42,23) = 966
