28.
20 and 28 both have six factors.
28 is a composite number because it has more than two factors but 29 is a prime number because it has only two factors.
7*4 A number which can go into a number is called a factor. factors of 28 = 1, 2, 4, 7, 14, 28 to find the factors of a certain number, divide this number by numbers from 1 to whatever the number is, and if the answer is an integer (whole number), it is a factor, e.g. 28: 28 divided by 4=7 therefore, both 4 and 7 are factors of 28 28 divided by 14=2 therefore 14 and 2 are factors of 28 28 divided by 28=1 therefore 28 and 1 are factors of 28 therefore, factors of 28 are 1, 28, 2, 14, 4, 7
The factors of 28 are: 1, 2, 4, 7, 14, 28.
28. The sum of its factors (smaller than 28) is 1 + 2 + 4 + 7 + 14 = 28.
840 has 32 different factors - including 1 and itself. The next highest has 28 factors.
20 and 28 both have six factors.
28 is a composite number because it has factors of 2 and 7.
The number 28 has 6 factors. Factors are numbers that can be multiplied together to get the original number. The factors of 28 are 1, 2, 4, 7, 14, and 28. This can be determined by finding all the pairs of numbers that multiply together to equal 28.
