:1,157
Now, list down the factors of 220
:1,2,4,5,10,11,20,22,44,55,110,220
Greatest Common Factor
We found the factors 157,220 . The biggest common factor number is the GCF number.
So the greatest common factor 157,220 is 1.
Lets's calculate LCM of 783,240
3 | 783, 240 |
261, 80 |
∴ So the LCM of the given numbers is 3 x 261 x 80 = 62640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/62640
Therefore, the GCF of Fractions 157/783,220/240 is 1/62640
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 783,240 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(783,240) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(783,240) x common factors =3 x 1 = 3
LCM(783,240) = ( 783 × 240 ) / 3
LCM(783,240) = 187920 / 3
LCM(783,240) = 62640
