So the greatest common factor 799,155 is 1.
Lets's calculate LCM of 575,755
5 | 575, 755 |
115, 151 |
∴ So the LCM of the given numbers is 5 x 115 x 151 = 86825
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/86825
Therefore, the GCF of Fractions 799/575,155/755 is 1/86825
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 575,755 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(575,755) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(575,755) x common factors =5 x 1 = 5
LCM(575,755) = ( 575 × 755 ) / 5
LCM(575,755) = 434125 / 5
LCM(575,755) = 86825
