So the greatest common factor 804,6890 is 2.
Lets's calculate LCM of 400,700
2 | 400, 700 |
2 | 200, 350 |
5 | 100, 175 |
5 | 20, 35 |
4, 7 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 5 x 4 x 7 = 2800
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2800
Therefore, the GCF of Fractions 804/400,6890/700 is 2/2800
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 400,700 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(400,700) = 100
common factors(in case of two or more numbers have common factors) = 1
GCF(400,700) x common factors =100 x 1 = 100
LCM(400,700) = ( 400 × 700 ) / 100
LCM(400,700) = 280000 / 100
LCM(400,700) = 2800
