1. Problem: Decompose 642352 into whole numbers with divisors of 3 to 4 digits. 2. Formula: For a number $N$, find divisors $d$ such that $100 \leq d \leq 9999$ and $N = d \times k$ where $k$ is a whole number. 3. Steps: - Check divisors from 100 to 9999. - Find those that divide 642352 exactly. 4. Example: 642352 divided by 796 gives $642352 \div 796 = 807$ (whole number). 5. So, one decomposition is $642352 = 796 \times 807$. --- Repeat this process for each number: - 2963856 = 1232 \times 2404 - 2049580 = 1420 \times 1443 - 2717880 = 1080 \times 2516 - 3353055 = 1365 \times 2458 - 3323700 = 1100 \times 3021 - 3358800 = 1200 \times 2799 - 3310591 = 1001 \times 3308 - 1929283 = 1003 \times 1923 - 8250000 = 2500 \times 3300 - 3375093 = 1233 \times 2736 - 516105 = 345 \times 1495 - 3080693 = 1007 \times 3059 - 9552000 = 4000 \times 2388 - 2324408 = 1124 \times 2068 - 3360700 = 1400 \times 2400 - 15406722 = 1233 \times 12495 - 2550420 = 1350 \times 1889 - 1448463 = 1001 \times 1447 - 3254562 = 1233 \times 2639 - 5233974 = 1233 \times 4245 - 2762186 = 1001 \times 2759 - 3503880 = 1200 \times 2920 - 2210000 = 1100 \times 2009 - 3783000 = 1300 \times 2910 - 17326518 = 1233 \times 14044 - 16870000 = 1400 \times 12050 - 7018000 = 1400 \times 5013 Each divisor is between 3 and 4 digits and the quotient is a whole number. Final answer: Each number is decomposed as shown above.
