Deepesh has 168 litres of Oil A and 234 litres of Oil B. He fills a number of identical containers with the two types of oil in a manner that each container has only one type of oil, and all containers are completely filled. What can be the maximum volume (in litres) of each container that Deepesh uses, so that all the oil that Deepesh has, of both the types, can be poured into these containers?

💡 Analysis & Explanation
Mathematical Premise
To find the maximum possible volume of a single identical container that can exactly measure two different liquid volumes without mixing, we must calculate the Highest Common Factor (HCF) of the two volumes.
Prime Factorization
For Oil A, 168 = 2³ × 3 × 7. For Oil B, 234 = 2 × 3² × 13.
HCF Calculation
The common prime factors are 2 and 3. Taking the lowest power of these common factors gives us 2¹ × 3¹ = 6.
Conclusion
The maximum capacity of each container must be exactly 6 litres.
