Greatest Common Factor
We found the factors 253,535 . The biggest common factor number is the GCF number.
So the greatest common factor 253,535 is 1.
Lets's calculate LCM of 490,815
5 | 490, 815 |
98, 163 |
∴ So the LCM of the given numbers is 5 x 98 x 163 = 79870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/79870
Therefore, the GCF of Fractions 253/490,535/815 is 1/79870
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 490,815 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(490,815) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(490,815) x common factors =5 x 1 = 5
LCM(490,815) = ( 490 × 815 ) / 5
LCM(490,815) = 399350 / 5
LCM(490,815) = 79870
