:1,3,5,15,43,129,215,645
Greatest Common Factor
We found the factors 14,22,645 . The biggest common factor number is the GCF number.
So the greatest common factor 14,22,645 is 1.
Lets's calculate LCM of 31,95,20
5 | 31, 95, 20 |
31, 19, 4 |
∴ So the LCM of the given numbers is 5 x 31 x 19 x 4 = 11780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11780
Therefore, the GCF of Fractions 14/31,22/95,645/20 is 1/11780
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 31,95,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,95,20) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(31,95,20) x common factors =1 x 5 = 5
LCM(31,95,20) = ( 31 × 95 × 20 ) / 5
LCM(31,95,20) = 58900 / 5
LCM(31,95,20) = 11780
