Lets's calculate LCM of 394,664,821
2 | 394, 664, 821 |
197, 332, 821 |
∴ So the LCM of the given numbers is 2 x 197 x 332 x 821 = 107393368
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/107393368
Therefore, the GCF of Fractions 37/394,42/664,129/821 is 1/107393368
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 394,664,821 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(394,664,821) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(394,664,821) x common factors =1 x 2 = 2
LCM(394,664,821) = ( 394 × 664 × 821 ) / 2
LCM(394,664,821) = 214786736 / 2
LCM(394,664,821) = 107393368
