So the greatest common factor 109,993 is 1.
Lets's calculate LCM of 640,456
2 | 640, 456 |
2 | 320, 228 |
2 | 160, 114 |
80, 57 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 80 x 57 = 36480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/36480
Therefore, the GCF of Fractions 109/640,993/456 is 1/36480
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 640,456 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(640,456) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(640,456) x common factors =8 x 1 = 8
LCM(640,456) = ( 640 × 456 ) / 8
LCM(640,456) = 291840 / 8
LCM(640,456) = 36480
