Assignment 4: Primes, Greatest Common Factors, and Least Common Multiples
Part 1
Step 1: Write down your CUNYFirst number. (For example, my CUNYFirst number could be 55011234)
Step 2: Replace all the 0’s in your CUNYFirst number with 2. (So my number will now be 55211234. If you do
not have any 0’s you do not need to replace anything.)
Step 3: Take your number from step 2 and break it up into 4 separate two-digit numbers. (I now have the four
numbers: 55, 21, 12, 34)
Part 2
Step 4: Add the four numbers from step 3. (I would add 55+21+12+34=122)
Step 5: Using the attached list of prime numbers, choose a prime number closest to the sum of step 4. (I see
the closest prime number to 122 is 127)
Step 6: Verify the number from step 5 is a prime number by using the prime number test.
Step 7: Multiply the two largest numbers from step 3. (I would multiply 55*34=1870)
Step 8: Using the attached list of prime numbers, choose a prime number closest to the product of step 7. (I see
the closest prime number to 1870 is 1871)
Step 9: Verify the number from step 8 is a prime number by using the prime number test.
