Lets's calculate LCM of 689,320
Given numbers has no common factors except 1. So, there LCM is their product i.e 220480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/220480
Therefore, the GCF of Fractions 801/689,4275/320 is 9/220480
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 689,320 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(689,320) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(689,320) x common factors =1 x 1 = 1
LCM(689,320) = ( 689 × 320 ) / 1
LCM(689,320) = 220480 / 1
LCM(689,320) = 220480
