Lets's calculate LCM of 829,257
Given numbers has no common factors except 1. So, there LCM is their product i.e 213053
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/213053
Therefore, the GCF of Fractions 470/829,636/257 is 2/213053
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 829,257 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(829,257) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(829,257) x common factors =1 x 1 = 1
LCM(829,257) = ( 829 × 257 ) / 1
LCM(829,257) = 213053 / 1
LCM(829,257) = 213053
