So the greatest common factor 417,874 is 1.
Lets's calculate LCM of 538,272
2 | 538, 272 |
269, 136 |
∴ So the LCM of the given numbers is 2 x 269 x 136 = 73168
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/73168
Therefore, the GCF of Fractions 417/538,874/272 is 1/73168
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 538,272 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(538,272) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(538,272) x common factors =2 x 1 = 2
LCM(538,272) = ( 538 × 272 ) / 2
LCM(538,272) = 146336 / 2
LCM(538,272) = 73168
