Lets's calculate LCM of 856,178
2 | 856, 178 |
428, 89 |
∴ So the LCM of the given numbers is 2 x 428 x 89 = 76184
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/76184
Therefore, the GCF of Fractions 682/856,240/178 is 2/76184
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 856,178 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(856,178) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(856,178) x common factors =2 x 1 = 2
LCM(856,178) = ( 856 × 178 ) / 2
LCM(856,178) = 152368 / 2
LCM(856,178) = 76184
