Lets's calculate LCM of 802,385
Given numbers has no common factors except 1. So, there LCM is their product i.e 308770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/308770
Therefore, the GCF of Fractions 715/802,874/385 is 1/308770
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 802,385 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(802,385) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(802,385) x common factors =1 x 1 = 1
LCM(802,385) = ( 802 × 385 ) / 1
LCM(802,385) = 308770 / 1
LCM(802,385) = 308770
