Greatest Common Factor
We found the factors 790,620 . The biggest common factor number is the GCF number.
So the greatest common factor 790,620 is 10.
Lets's calculate LCM of 950,408
2 | 950, 408 |
475, 204 |
∴ So the LCM of the given numbers is 2 x 475 x 204 = 193800
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/193800
Therefore, the GCF of Fractions 790/950,620/408 is 10/193800
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 950,408 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(950,408) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(950,408) x common factors =2 x 1 = 2
LCM(950,408) = ( 950 × 408 ) / 2
LCM(950,408) = 387600 / 2
LCM(950,408) = 193800
