Greatest Common Factor
We found the factors 80,97,77,29 . The biggest common factor number is the GCF number.
So the greatest common factor 80,97,77,29 is 1.
Lets's calculate LCM of 14,80,86,120
2 | 14, 80, 86, 120 |
2 | 7, 40, 43, 60 |
2 | 7, 20, 43, 30 |
5 | 7, 10, 43, 15 |
7, 2, 43, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 7 x 2 x 43 x 3 = 72240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/72240
Therefore, the GCF of Fractions 80/14,97/80,77/86,29/120 is 1/72240
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 14,80,86,120 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(14,80,86,120) = 2
common factors(in case of two or more numbers have common factors) = 80
GCF(14,80,86,120) x common factors =2 x 80 = 160
LCM(14,80,86,120) = ( 14 × 80 × 86 × 120 ) / 160
LCM(14,80,86,120) = 11558400 / 160
LCM(14,80,86,120) = 72240
