Find the highest common factor of $$1750 and $$4900.

Sure, here are the steps to find the highest common factor (HCF) of 1750 and 4900:

Step 1: Write down the prime factors of each number.

• Prime factors of 1750: 2, 5, 5, 5, 7
• Prime factors of 4900: 2, 2, 5, 5, 7, 7

Step 2: Identify the common factors.

• The common factors are: 2, 5, 5, 7

Step 3: Multiply the common factors together to get the HCF.

• HCF = 2 * 5 * 5 * 7 = 350

So, the highest common factor of 1750 and 4900 is 350.
