Prime Factorisation of the Smallest Three-Digit Number
Factors of a number are the numbers that can be multiplied together to get that number. Factorisation of a number may not be unique because a number can be expressed as a product of different combinations of its factors. However, the prime factorisation of a number is unique because every composite number can be expressed as a product of prime numbers in only one way.
Factorisation of the Smallest Three-Digit Number (100)
- The smallest three-digit number is 100.
- Factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.
- One possible factorisation of 100 is 2 x 2 x 5 x 5.
- Another possible factorisation of 100 is 4 x 5 x 5.
- Both factorisations are valid since they result in 100.
Prime Factorisation of 100
- Prime factorisation of 100 involves expressing 100 as a product of prime numbers.
- The prime factors of 100 are 2 and 5.
- Prime factorisation of 100 is 2 x 2 x 5 x 5.
- This prime factorisation is unique because the prime factors are 2 and 5, and they are prime numbers.
Therefore, the factorisation of a number may not be unique, but the prime factorisation of a number is unique. The prime factorisation of the smallest three-digit number, 100, is 2 x 2 x 5 x 5.
