Eight numbers are factors of 40, including 1, 2 and 4. Other factors of 40 are 5, 8, 10, 20 and 40.
Know MoreThe factors of a number are those that divide evenly into the number in question. To factor a number, it is expressed as a product of smaller numbers which is referred to as factorization. For example, factoring the number 12 would result in 3 x 4, but it can be further factored as 12 = 2 x 2 x 3. If a number can not be factored any further, it is known as a prime number. The greatest common factor is the greatest number that two numbers have in common. For instance, the greatest common factor of 16 and 12 is 4 because it is the largest number that can be evenly divided into both numbers.

Full Answer >The factors of 32 are 1, 2, 4, 8, 16 and 32. Factoring in mathematics is the process of disassembling a number or expression into constituent parts that, when multiplied, result in the original. In this case, 32 can be reached by multiplying 4 with 8, 2 with 16, and 1 with 32.
Full Answer >The factors of 16 are 1, 2, 4, 8 and 16. The number 16 has the uncommon trait of having an odd number of factors because it's a square number.
Full Answer >The factors of 46 are 1, 2, 23 and 46, as well as -1, -2, -23 and -46. Factors are numbers that are multiplied to obtain another number. Negative numbers can also be factors, because a negative number times another negative number will produce a positive number.
