Greatest Common Factor
We found the factors 940,515 . The biggest common factor number is the GCF number.
So the greatest common factor 940,515 is 5.
Lets's calculate LCM of 722,620
2 | 722, 620 |
361, 310 |
∴ So the LCM of the given numbers is 2 x 361 x 310 = 223820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/223820
Therefore, the GCF of Fractions 940/722,515/620 is 5/223820
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 722,620 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(722,620) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(722,620) x common factors =2 x 1 = 2
LCM(722,620) = ( 722 × 620 ) / 2
LCM(722,620) = 447640 / 2
LCM(722,620) = 223820
