Greatest Common Factor
We found the factors 1668,4680 . The biggest common factor number is the GCF number.
So the greatest common factor 1668,4680 is 12.
Lets's calculate LCM of 841,3906
Given numbers has no common factors except 1. So, there LCM is their product i.e 3284946
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/3284946
Therefore, the GCF of Fractions 1668/841,4680/3906 is 12/3284946
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 841,3906 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(841,3906) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(841,3906) x common factors =1 x 1 = 1
LCM(841,3906) = ( 841 × 3906 ) / 1
LCM(841,3906) = 3284946 / 1
LCM(841,3906) = 3284946
