So the greatest common factor 742,819 is 7.
Lets's calculate LCM of 23,6340
Given numbers has no common factors except 1. So, there LCM is their product i.e 145820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/145820
Therefore, the GCF of Fractions 742/23,819/6340 is 7/145820
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 23,6340 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,6340) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(23,6340) x common factors =1 x 1 = 1
LCM(23,6340) = ( 23 × 6340 ) / 1
LCM(23,6340) = 145820 / 1
LCM(23,6340) = 145820
