Lets's calculate LCM of 708,621,369
3 | 708, 621, 369 |
3 | 236, 207, 123 |
236, 69, 41 |
∴ So the LCM of the given numbers is 3 x 3 x 236 x 69 x 41 = 6008796
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6008796
Therefore, the GCF of Fractions 418/708,408/621,839/369 is 1/6008796
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 708,621,369 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(708,621,369) = 3
common factors(in case of two or more numbers have common factors) = 9
GCF(708,621,369) x common factors =3 x 9 = 27
LCM(708,621,369) = ( 708 × 621 × 369 ) / 27
LCM(708,621,369) = 162237492 / 27
LCM(708,621,369) = 6008796
