Lets's calculate LCM of 740,881
Given numbers has no common factors except 1. So, there LCM is their product i.e 651940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/651940
Therefore, the GCF of Fractions 804/740,2121/881 is 3/651940
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 740,881 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(740,881) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(740,881) x common factors =1 x 1 = 1
LCM(740,881) = ( 740 × 881 ) / 1
LCM(740,881) = 651940 / 1
LCM(740,881) = 651940
Here are some samples of GCF of Fractions calculations.
