Lets's calculate LCM of 674,415
Given numbers has no common factors except 1. So, there LCM is their product i.e 279710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/279710
Therefore, the GCF of Fractions 820/674,4095/415 is 5/279710
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 674,415 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(674,415) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(674,415) x common factors =1 x 1 = 1
LCM(674,415) = ( 674 × 415 ) / 1
LCM(674,415) = 279710 / 1
LCM(674,415) = 279710
