Greatest Common Factor
We found the factors 380,3902 . The biggest common factor number is the GCF number.
So the greatest common factor 380,3902 is 2.
Lets's calculate LCM of 545,800
5 | 545, 800 |
109, 160 |
∴ So the LCM of the given numbers is 5 x 109 x 160 = 87200
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/87200
Therefore, the GCF of Fractions 380/545,3902/800 is 2/87200
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 545,800 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(545,800) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(545,800) x common factors =5 x 1 = 5
LCM(545,800) = ( 545 × 800 ) / 5
LCM(545,800) = 436000 / 5
LCM(545,800) = 87200
