Greatest Common Factor
We found the factors 691,420 . The biggest common factor number is the GCF number.
So the greatest common factor 691,420 is 1.
Lets's calculate LCM of 402,326
2 | 402, 326 |
201, 163 |
∴ So the LCM of the given numbers is 2 x 201 x 163 = 65526
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/65526
Therefore, the GCF of Fractions 691/402,420/326 is 1/65526
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 402,326 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(402,326) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(402,326) x common factors =2 x 1 = 2
LCM(402,326) = ( 402 × 326 ) / 2
LCM(402,326) = 131052 / 2
LCM(402,326) = 65526
