Lets's calculate LCM of 394,842
2 | 394, 842 |
197, 421 |
∴ So the LCM of the given numbers is 2 x 197 x 421 = 165874
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/165874
Therefore, the GCF of Fractions 735/394,668/842 is 1/165874
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 394,842 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(394,842) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(394,842) x common factors =2 x 1 = 2
LCM(394,842) = ( 394 × 842 ) / 2
LCM(394,842) = 331748 / 2
LCM(394,842) = 165874
