:1,2,4,5,10,20
Greatest Common Factor
We found the factors 36,20 . The biggest common factor number is the GCF number.
So the greatest common factor 36,20 is 4.
Lets's calculate LCM of 470,4798
2 | 470, 4798 |
235, 2399 |
∴ So the LCM of the given numbers is 2 x 235 x 2399 = 1127530
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/1127530
Therefore, the GCF of Fractions 36/470,20/4798 is 4/1127530
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 470,4798 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(470,4798) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(470,4798) x common factors =2 x 1 = 2
LCM(470,4798) = ( 470 × 4798 ) / 2
LCM(470,4798) = 2255060 / 2
LCM(470,4798) = 1127530
