Lets's calculate LCM of 889,457
Given numbers has no common factors except 1. So, there LCM is their product i.e 406273
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/406273
Therefore, the GCF of Fractions 659/889,640/457 is 1/406273
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 889,457 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(889,457) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(889,457) x common factors =1 x 1 = 1
LCM(889,457) = ( 889 × 457 ) / 1
LCM(889,457) = 406273 / 1
LCM(889,457) = 406273
