Lets's calculate LCM of 450,774
2 | 450, 774 |
3 | 225, 387 |
3 | 75, 129 |
25, 43 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 25 x 43 = 19350
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19350
Therefore, the GCF of Fractions 757/450,438/774 is 1/19350
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 450,774 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(450,774) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(450,774) x common factors =18 x 1 = 18
LCM(450,774) = ( 450 × 774 ) / 18
LCM(450,774) = 348300 / 18
LCM(450,774) = 19350
