Lets's calculate LCM of 898,143,633
Given numbers has no common factors except 1. So, there LCM is their product i.e 81286062
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/81286062
Therefore, the GCF of Fractions 20/898,66/143,874/633 is 2/81286062
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 898,143,633 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(898,143,633) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(898,143,633) x common factors =1 x 1 = 1
LCM(898,143,633) = ( 898 × 143 × 633 ) / 1
LCM(898,143,633) = 81286062 / 1
LCM(898,143,633) = 81286062
