Lets's calculate LCM of 639,621
3 | 639, 621 |
3 | 213, 207 |
71, 69 |
∴ So the LCM of the given numbers is 3 x 3 x 71 x 69 = 44091
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/44091
Therefore, the GCF of Fractions 844/639,980/621 is 4/44091
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 639,621 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(639,621) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(639,621) x common factors =9 x 1 = 9
LCM(639,621) = ( 639 × 621 ) / 9
LCM(639,621) = 396819 / 9
LCM(639,621) = 44091
