Lets's calculate LCM of 820,7551
Given numbers has no common factors except 1. So, there LCM is their product i.e 6191820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/6191820
Therefore, the GCF of Fractions 2330/820,1242/7551 is 2/6191820
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 820,7551 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(820,7551) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(820,7551) x common factors =1 x 1 = 1
LCM(820,7551) = ( 820 × 7551 ) / 1
LCM(820,7551) = 6191820 / 1
LCM(820,7551) = 6191820
