Lets's calculate LCM of 634,511
Given numbers has no common factors except 1. So, there LCM is their product i.e 323974
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/323974
Therefore, the GCF of Fractions 561/634,7875/511 is 3/323974
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 634,511 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(634,511) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(634,511) x common factors =1 x 1 = 1
LCM(634,511) = ( 634 × 511 ) / 1
LCM(634,511) = 323974 / 1
LCM(634,511) = 323974
Here are some samples of GCF of Fractions calculations.
