Lets's calculate LCM of 70,23,543
Given numbers has no common factors except 1. So, there LCM is their product i.e 874230
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/874230
Therefore, the GCF of Fractions 84/70,480/23,746/543 is 2/874230
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 70,23,543 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,23,543) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(70,23,543) x common factors =1 x 1 = 1
LCM(70,23,543) = ( 70 × 23 × 543 ) / 1
LCM(70,23,543) = 874230 / 1
LCM(70,23,543) = 874230
