This is a calculus question. You would need to use an integral.
A number n for which the sum of all the positive integer factors of n which are less than n add up to n.For example, 6 and 28 are perfect numbers. The number 6 has factors 1, 2, and 3, and 1 + 2 + 3 = 6. The number 28 has factors 1, 2, 4, 7, and 14, and 1 + 2 + 4 + 7 + 14 = 28
40 meters is greater than 40 cm
40 by 40 feet = 1,600 square feet = 148.64 square meters.
No, 40 mile radius is an area unit whereas 40 mile is distance. This means that something 30 miles from a location can be said to be in a 40 mile radius from that location.
3,000,000 has 98 positive integral factors.
they are simply the factors of a number

Eight of them.

A composite number is a number with more than two positive integer factors, including itself and 1. Since 40 is divisible by 2, it is a composite number. The positive integer factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
An integral number is an integer. A whole number positive, negative or zero.
36 has 8 positive, integral factors:1, 2, 3, 4, 9, 12, 18, 36=========================Addendum:The mathematical world was stunned today at the announcement that anotherpositive integral factor of 36 has been identified. Investigators at Lincoln #22elementary school in Rochester NY have proven that ' 6 ' is included in thatcategory. Textbooks will now need to be revised to reflect the true numberof factors of 36 as nine, instead of the eight that we were all taught. Journalistsare already referring ironically to the number ' 6 ' as the "Pluto factor".
The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. So yes 5 is a factor of 40.
