So the greatest common factor 85,190,589 is 1.
Lets's calculate LCM of 802,660,638
2 | 802, 660, 638 |
11 | 401, 330, 319 |
401, 30, 29 |
∴ So the LCM of the given numbers is 2 x 11 x 401 x 30 x 29 = 7675140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7675140
Therefore, the GCF of Fractions 85/802,190/660,589/638 is 1/7675140
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 802,660,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(802,660,638) = 2
common factors(in case of two or more numbers have common factors) = 22
GCF(802,660,638) x common factors =2 x 22 = 44
LCM(802,660,638) = ( 802 × 660 × 638 ) / 44
LCM(802,660,638) = 337706160 / 44
LCM(802,660,638) = 7675140
