Two tankers contain 850 litres and 680 liters of kerosene oil Respectively. Find the maximum capacity of a container which can measure the kerosene oil of both the tankers when used an exact number of times.

Explanation

To find the maximum capacity of a container that can measure the kerosene oil from both tankers (850 liters and 680 liters) in exact numbers, we need to determine the highest common factor (HCF) of the two quantities. Here’s how to do it step by step:

### Step 1: Find the prime factorization of both numbers.

**For 850:**
- Divide by 2: \( 850 \div 2 = 425 \)
- Divide by 5: \( 425 \div 5 = 85 \)
- Divide by 5 again: \( 85 \div 5 = 17 \)
