Lets's calculate LCM of 706,685
Given numbers has no common factors except 1. So, there LCM is their product i.e 483610
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/483610
Therefore, the GCF of Fractions 558/706,8457/685 is 3/483610
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 706,685 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(706,685) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(706,685) x common factors =1 x 1 = 1
LCM(706,685) = ( 706 × 685 ) / 1
LCM(706,685) = 483610 / 1
LCM(706,685) = 483610
Here are some samples of GCF of Fractions calculations.
