1,2, and 4 will.
The common factors of 68 and 80 are 1, 2, and 4 . Next time you ask me to pick the correct item from a list of multiple choices for you, I'm going to expect you to show me the list.
566 ÷ 81 = 6.987654321 (Or 566 ÷ 81 = 6 remainder 80.)
There are 10 numbers between 10 and 80 that are divisible by 7 with no remainder: 14, 21, 28, 35, 42, 49, 56, 63, 70, and 77.
78. add up all the numbers and then divide by the number of numbers you added.
The highest common factor is the greatest number which both numbers can divide by evenly. In this case, the greatest number 40 can divide by is 40. 80 can also divide by 40, and so this is a common factor. As no numbers greater than 40 will be able to divide 40 evenly, the hcf of 40 and 80 is 40.
As there are 12 inches in 1 foot, divide the length in inches by 12 to give a whole number quotient and remainder; the quotient is the number of feet and the remainder is the number of inches. eg if the couch was 80 inches long, then: 80 ÷ 12 = 6 r 8 (since 6 × 12 + 8 = 72 + 8 = 80) → 80 inches = 6 ft 8 in.
As 1209 is 39 x 31 and 62 = 2 x 31, the answer is zero. As an example divide 2480 by 1209, answer 2 remainder 62; Now divide it by 31, answer 80 no remainder.
Divide both numbers by their HCF. So 80/100 = 4/5
Those are the "factors" of 80. They are: 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80.
