So the greatest common factor 40,867,825 is 1.
Lets's calculate LCM of 812,394,407
2 | 812, 394, 407 |
406, 197, 407 |
∴ So the LCM of the given numbers is 2 x 406 x 197 x 407 = 65105348
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/65105348
Therefore, the GCF of Fractions 40/812,867/394,825/407 is 1/65105348
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 812,394,407 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(812,394,407) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(812,394,407) x common factors =1 x 2 = 2
LCM(812,394,407) = ( 812 × 394 × 407 ) / 2
LCM(812,394,407) = 130210696 / 2
LCM(812,394,407) = 65105348
