1,3,7,21,47,141,329,987
Greatest Common Factor
We found the factors 74,60,31,987 . The biggest common factor number is the GCF number.
So the greatest common factor 74,60,31,987 is 1.
Lets's calculate LCM of 80,85,86,85
2 | 80, 85, 86, 85 |
5 | 40, 85, 43, 85 |
17 | 8, 17, 43, 17 |
8, 1, 43, 1 |
∴ So the LCM of the given numbers is 2 x 5 x 17 x 8 x 1 x 43 x 1 = 58480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/58480
Therefore, the GCF of Fractions 74/80,60/85,31/86,987/85 is 1/58480
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 80,85,86,85 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,85,86,85) = 1
common factors(in case of two or more numbers have common factors) = 850
GCF(80,85,86,85) x common factors =1 x 850 = 850
LCM(80,85,86,85) = ( 80 × 85 × 86 × 85 ) / 850
LCM(80,85,86,85) = 49708000 / 850
LCM(80,85,86,85) = 58480
