Question

if d is the difference between greatest four digit number and least five digit number whose HCF is 163. then find the LCM of 815,3d,326​

Answer 1

The LCM is "4890".

Step-by-step explanation:

Given,

HCF = 163

The difference between greatest four digit number and least five digit number(d) = 1,0000 - 9,999 = 1

We know that,

LCM × HCF = Product of numbers

⇒ LCM × 163 = 815 × 3(1) × 326​

⇒ LCM = 815 × 3 × 2

⇒ LCM = 815 × 6

⇒ LCM = 4890

∴ LCM = 4890

Hence, the LCM is 4890.
