Lets's calculate LCM of 640,806
2 | 640, 806 |
320, 403 |
∴ So the LCM of the given numbers is 2 x 320 x 403 = 257920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/257920
Therefore, the GCF of Fractions 220/640,2796/806 is 4/257920
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 640,806 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(640,806) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(640,806) x common factors =2 x 1 = 2
LCM(640,806) = ( 640 × 806 ) / 2
LCM(640,806) = 515840 / 2
LCM(640,806) = 257920
