:1,3,277,831
Greatest Common Factor
We found the factors 33,247,831 . The biggest common factor number is the GCF number.
So the greatest common factor 33,247,831 is 1.
Lets's calculate LCM of 49,77,821
7 | 49, 77, 821 |
7, 11, 821 |
∴ So the LCM of the given numbers is 7 x 7 x 11 x 821 = 442519
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/442519
Therefore, the GCF of Fractions 33/49,247/77,831/821 is 1/442519
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 49,77,821 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,77,821) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(49,77,821) x common factors =1 x 7 = 7
LCM(49,77,821) = ( 49 × 77 × 821 ) / 7
LCM(49,77,821) = 3097633 / 7
LCM(49,77,821) = 442519
