What number has exactly 8 factors?
24=2*2*2*3 has 8 factors: 1, 2, 3, 4, 6, 8, 12, 24. 24 is the smallest number with 8 factors, as simple verification for numbers below 24 show 24 is first one with this property.
What are factors the factors of 8?
The factors of 8 are 1, 2, 4, and 8. 1 is a universal factor because it is a factor of all numbers. Factors are quite often given as pairs of numbers which when multiplied together give the original number.
What are factors of 20?
Hence, the factors of 20 are 1, 2, 4, 5, 10, and 20. Important Notes: Factors of a number are all the possible numbers it is divisible by. They may be prime numbers or composite numbers.
What is the least possible value that has exactly 8 factors?
24
Therefore, smallest number that has exactly 8 factors = 24.

What are the factors of 2?
What is the factor of 2?
Factors of 2 are 1 and 2 only. (-1 , -2) are also factors of 2 as the product of any two negative numbers gives a positive number.
What are all the multiples of 20?
The multiples of 20 are 20, 40, 60, 80, 100, 120, 140 and so on.
How many factors does a number have exactly?
A number has exactly eight factors. Two of the factors are 8 and 20. What are all the factors of the number? If 8 is a factor, then so are 2 and 4. If 20 is a factor, then so are 5 and 10. 1 must be a factor by default.
What is a number with 8 factors and 8 divisors?
A number with eight factors is a*b*c*d*e*f*g*h*i. Of which two are a=8, b=20. A number with eight divisors has 8 integers that divide it include itself and 1.
What are all the factors of N?
Suppose N has exactly eight factors, including 8 and 20. Then all factors of 8 and all factors of 20 are also factors of N, and N must be a multiple of the lcm [ 8, 20]. Thus 1, 2, 4, 5, and 10 are also factors of N, and N is a multiple of 40.
What is the least common multiple of 8 and 20?
The least common multiple of the numbers 8 and 20 is 40. The factors are 1, 2, 4, 5, 8, 10, 20, 40. Factors of a number are the possible numbers which can divide the given number without leaving any remainders. Here the numbers 8 and 20 gives L.C.M which gives exactly right factors.
