So the greatest common factor 850,438,309 is 1.
Lets's calculate LCM of 625,725,310
5 | 625, 725, 310 |
5 | 125, 145, 62 |
25, 29, 62 |
∴ So the LCM of the given numbers is 5 x 5 x 25 x 29 x 62 = 1123750
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1123750
Therefore, the GCF of Fractions 850/625,438/725,309/310 is 1/1123750
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 625,725,310 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(625,725,310) = 5
common factors(in case of two or more numbers have common factors) = 25
GCF(625,725,310) x common factors =5 x 25 = 125
LCM(625,725,310) = ( 625 × 725 × 310 ) / 125
LCM(625,725,310) = 140468750 / 125
LCM(625,725,310) = 1123750
