Lets's calculate LCM of 229,778
Given numbers has no common factors except 1. So, there LCM is their product i.e 178162
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 27/178162
Therefore, the GCF of Fractions 648/229,621/778 is 27/178162
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 229,778 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(229,778) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(229,778) x common factors =1 x 1 = 1
LCM(229,778) = ( 229 × 778 ) / 1
LCM(229,778) = 178162 / 1
LCM(229,778) = 178162
