Q. Which numbers are factors of 2020 ? Select all that apply.\newline1717\newline55\newline99\newline77
  1. Checking if 1717 is a factor: To determine if a number is a factor of 2020, we need to check if 2020 can be divided by that number without leaving a remainder.\newlineLet's start with the number 1717.\newlineWe divide 2020 by 1717 and see if the remainder is 00.\newline20÷17=120 \div 17 = 1 with a remainder of 33.\newlineSince there is a remainder, 1717 is not a factor of 2020.
  2. Checking if 55 is a factor: Next, we check if 55 is a factor of 2020. We divide 2020 by 55 and see if the remainder is 00. 20÷5=420 \div 5 = 4 with no remainder. Since there is no remainder, 55 is a factor of 2020.
  3. Checking if 99 is a factor: Now, let's check if 99 is a factor of 2020. We divide 2020 by 99 and see if the remainder is 00. 20÷9=220 \div 9 = 2 with a remainder of 22. Since there is a remainder, 99 is not a factor of 2020.
  4. Checking if 77 is a factor: Finally, we check if 77 is a factor of 2020. We divide 2020 by 77 and see if the remainder is 00. 20÷7=220 \div 7 = 2 with a remainder of 66. Since there is a remainder, 77 is not a factor of 2020.
