Greatest Common Factor
We found the factors 85,335,768 . The biggest common factor number is the GCF number.
So the greatest common factor 85,335,768 is 1.
Lets's calculate LCM of 21,56,798
2 | 21, 56, 798 |
3 | 21, 28, 399 |
7 | 7, 28, 133 |
1, 4, 19 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 4 x 19 = 3192
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3192
Therefore, the GCF of Fractions 85/21,335/56,768/798 is 1/3192
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 21,56,798 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,56,798) = 7
common factors(in case of two or more numbers have common factors) = 42
GCF(21,56,798) x common factors =7 x 42 = 294
LCM(21,56,798) = ( 21 × 56 × 798 ) / 294
LCM(21,56,798) = 938448 / 294
LCM(21,56,798) = 3192
