So the greatest common factor 646,1740 is 2.
Lets's calculate LCM of 414,9631
Given numbers has no common factors except 1. So, there LCM is their product i.e 3987234
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/3987234
Therefore, the GCF of Fractions 646/414,1740/9631 is 2/3987234
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 414,9631 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(414,9631) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(414,9631) x common factors =1 x 1 = 1
LCM(414,9631) = ( 414 × 9631 ) / 1
LCM(414,9631) = 3987234 / 1
LCM(414,9631) = 3987234
