Lets's calculate LCM of 920,781
Given numbers has no common factors except 1. So, there LCM is their product i.e 718520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/718520
Therefore, the GCF of Fractions 416/920,585/781 is 13/718520
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 920,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(920,781) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(920,781) x common factors =1 x 1 = 1
LCM(920,781) = ( 920 × 781 ) / 1
LCM(920,781) = 718520 / 1
LCM(920,781) = 718520
