Lets's calculate LCM of 445,292
Given numbers has no common factors except 1. So, there LCM is their product i.e 129940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 45/129940
Therefore, the GCF of Fractions 630/445,765/292 is 45/129940
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 445,292 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(445,292) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(445,292) x common factors =1 x 1 = 1
LCM(445,292) = ( 445 × 292 ) / 1
LCM(445,292) = 129940 / 1
LCM(445,292) = 129940
