Lets's calculate LCM of 492,685
Given numbers has no common factors except 1. So, there LCM is their product i.e 337020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/337020
Therefore, the GCF of Fractions 644/492,8638/685 is 14/337020
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 492,685 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(492,685) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(492,685) x common factors =1 x 1 = 1
LCM(492,685) = ( 492 × 685 ) / 1
LCM(492,685) = 337020 / 1
LCM(492,685) = 337020
