Greatest Common Factor
We found the factors 34,660,394 . The biggest common factor number is the GCF number.
So the greatest common factor 34,660,394 is 2.
Lets's calculate LCM of 22,80,117
2 | 22, 80, 117 |
11, 40, 117 |
∴ So the LCM of the given numbers is 2 x 11 x 40 x 117 = 102960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/102960
Therefore, the GCF of Fractions 34/22,660/80,394/117 is 2/102960
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 22,80,117 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(22,80,117) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(22,80,117) x common factors =1 x 2 = 2
LCM(22,80,117) = ( 22 × 80 × 117 ) / 2
LCM(22,80,117) = 205920 / 2
LCM(22,80,117) = 102960
