What Are the Factors of 10?

The factors of 10 are 1, 2, 5, and 10.

Hence, 10 has four factors. Unlike the other numbers, 10 is a composite number. If the given number is a composite number, then it has more than 2 factors, apart from 1 and the number itself. The factors of 10 has both positive and negative factors, and they are:

• Positive Factors of 10: 1, 2, 5, and 10.
• Negative Factors of 10: -1, -2, -5 and -10.
• Prime Factorization of 10: 2 X 5
• Prime Factors of 10: 2, 5
• Sum of Factors of 10: 8
• Sum of Prime factors of 10: 7

Write Factors of 10 in Pairs

As we said, factors can be negative or positive, and the same goes for pairs as well. These pairs are the ones we get 10 as factors after we multiply them.

Positive Pair Factor of 10

The positive pair factors of 10 are (1,10), (2,5), (5,2), (10,1).

Negative Pair Factors of 10

The negative pair factors of 10 are (-1,-10), (-2,-5), (-5,-2), (-10,-1).

How To Find Factors of 10 by Division Method?

To find factors of 10, we need to divide the number 10 by the sequence of the natural numbers till 10. The numbers which give the remainder are not factors of 10. Those numbers which doesn’t leave any remainder are the numbers known as factors of 10. The detailed steps to find the factors of 10 by the division method are given below:

• 10/1 = 10 (Remainder = 0)
• 10/2 = 5 (Remainder = 0)
• 10/3 = 9 (Remainder = 1)
• 10/4 = 8 (Remainder = 2)
• 10/5 = 2 (Remainder = 0)
• 10/6 = 1 (Remainder = 4)
• 10/10 = 1 (Remainder = 0)

Hence from the above division, it is clear that the numbers 1, 2, 5, and 10 don’t leave any remainder. Hence, the factors of 10 are 1, 2, 5, and 10.

Method 2 to Find Factors of 10

• Step 1: Write the number 10 and any two numbers that, when multiplied together, give the result 10.
• Step 2: Using the pair factors, we are choosing 2 and 5, because 2 x 5 = 10.
• Step 3: The numbers 2 and 5 are prime numbers, so they don’t have any factors except for the number 1 and itself.
  • 2 x 1 = 2
  • 5 x 1 = 5
• Step 4: Since we cannot factorise the prime numbers any more, the factors of 10 are 1, 2, 5, and 10.

How To Find Prime Factorisation of 10?

The steps to find the prime factorization of 10 is given below:

• Step 1: Firstly, we will find a small prime number that is divisible by 10. Hence we are dividing 10 with 2, which the smallest prime number.
  • 10 ÷ 2 = 5
• Step 2: Since we cannot divide 5 by 2, we will choose the next smallest prime number, which is 5, to divide by 5.
  • 5 ÷ 5 = 1
• Step 3: We conclude that 2 and 5 are the prime numbers of 10, because we cannot divide it further.

Hence the prime factors of 10 are 2 X 5 =10. The prime factors of 10 are 2 and 5.

Find the Factor Tree of 10

The steps to find a factor tree of 10 is given below:

• Step 1: Firstly, write the number 10 at the top of the factor tree
• Step 2: Now, as the part of the tree’s branches, write down the pair factors of 10 that 10 is divisible by. The pair factors we have used here is 2 and 5.
• Step 3: Since 2 and 5 are prime numbers, we cannot divide them anymore.

Circling all the branches gives us factors 2, and 5. Therefore, the prime factors of 10 using a factor tree are 2 X 5 = 10.
