Lets's calculate LCM of 896,169
Given numbers has no common factors except 1. So, there LCM is their product i.e 151424
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/151424
Therefore, the GCF of Fractions 402/896,497/169 is 1/151424
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 896,169 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(896,169) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(896,169) x common factors =1 x 1 = 1
LCM(896,169) = ( 896 × 169 ) / 1
LCM(896,169) = 151424 / 1
LCM(896,169) = 151424
