Lets's calculate LCM of 668,550,915
2 | 668, 550, 915 |
5 | 334, 275, 915 |
334, 55, 183 |
∴ So the LCM of the given numbers is 2 x 5 x 334 x 55 x 183 = 33617100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/33617100
Therefore, the GCF of Fractions 500/668,668/550,512/915 is 4/33617100
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 668,550,915 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(668,550,915) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(668,550,915) x common factors =1 x 10 = 10
LCM(668,550,915) = ( 668 × 550 × 915 ) / 10
LCM(668,550,915) = 336171000 / 10
LCM(668,550,915) = 33617100
