Greatest Common Factor
We found the factors 842,731 . The biggest common factor number is the GCF number.
So the greatest common factor 842,731 is 1.
Lets's calculate LCM of 520,955
5 | 520, 955 |
104, 191 |
∴ So the LCM of the given numbers is 5 x 104 x 191 = 99320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/99320
Therefore, the GCF of Fractions 842/520,731/955 is 1/99320
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 520,955 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(520,955) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(520,955) x common factors =5 x 1 = 5
LCM(520,955) = ( 520 × 955 ) / 5
LCM(520,955) = 496600 / 5
LCM(520,955) = 99320
