:1,821
Greatest Common Factor
We found the factors 897,821 . The biggest common factor number is the GCF number.
So the greatest common factor 897,821 is 1.
Lets's calculate LCM of 74,940
2 | 74, 940 |
37, 470 |
∴ So the LCM of the given numbers is 2 x 37 x 470 = 34780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/34780
Therefore, the GCF of Fractions 897/74,821/940 is 1/34780
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 74,940 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,940) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(74,940) x common factors =2 x 1 = 2
LCM(74,940) = ( 74 × 940 ) / 2
LCM(74,940) = 69560 / 2
LCM(74,940) = 34780
