So the greatest common factor 165,272 is 1.
Lets's calculate LCM of 310,128
2 | 310, 128 |
155, 64 |
∴ So the LCM of the given numbers is 2 x 155 x 64 = 19840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19840
Therefore, the GCF of Fractions 165/310,272/128 is 1/19840
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 310,128 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(310,128) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(310,128) x common factors =2 x 1 = 2
LCM(310,128) = ( 310 × 128 ) / 2
LCM(310,128) = 39680 / 2
LCM(310,128) = 19840
