Lets's calculate LCM of 670,878
2 | 670, 878 |
335, 439 |
∴ So the LCM of the given numbers is 2 x 335 x 439 = 294130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/294130
Therefore, the GCF of Fractions 255/670,326/878 is 1/294130
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 670,878 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(670,878) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(670,878) x common factors =2 x 1 = 2
LCM(670,878) = ( 670 × 878 ) / 2
LCM(670,878) = 588260 / 2
LCM(670,878) = 294130
