So the greatest common factor 86,636,858 is 2.
Lets's calculate LCM of 80,66,730
2 | 80, 66, 730 |
5 | 40, 33, 365 |
8, 33, 73 |
∴ So the LCM of the given numbers is 2 x 5 x 8 x 33 x 73 = 192720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/192720
Therefore, the GCF of Fractions 86/80,636/66,858/730 is 2/192720
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 80,66,730 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,66,730) = 2
common factors(in case of two or more numbers have common factors) = 10
GCF(80,66,730) x common factors =2 x 10 = 20
LCM(80,66,730) = ( 80 × 66 × 730 ) / 20
LCM(80,66,730) = 3854400 / 20
LCM(80,66,730) = 192720
