## What is the greatest prime factor of 1000?

Use prime factorization to find the greatest prime factor of 1000: 1000 = 2 × 2 × 2 × 5 × 5 × 5. The greatest prime factor of 1000 is 5.

## How many factors are there in 1000?

Hence, the factors of 1000 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 250, 500 and 1000. Thus, the total number of factors are 16.

**What is the prime factorisation 9999?**

Solution: Since, the prime factors of 9999 are 3, 11, 101. Therefore, the product of prime factors = 3 × 11 × 101 = 3333.

### Does the number 1000 have 4 factors of 10?

We know, the factors of 1000 also divisible by 10 are 10, 20, 40, 50, 100, 200, 250, 500, and 1000. Example 2: What are the total positive pairs of factors of 1000?…Factors of 1000 in Pairs.

Pair Factorization | Factor Pair |
---|---|

4 × 250 = 1000 | (4, 250) |

5 × 200 = 1000 | (5, 200) |

8 × 125 = 1000 | (8, 125) |

10× 100 = 1000 | (10, 100) |

### Which prime is least odd?

3

3 is the smallest odd prime number.

**Which is the smallest 5 multiple of 7?**

Answer. 10003 is the smallest 5-digit multiple of 7.

#### How do you solve for LCM?

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

#### How do you find prime factorization easily?

Step 1: Divide the given number by the smallest prime number. In this case, the smallest prime number should divide the number exactly. Step 2: Again, divide the quotient by the smallest prime number. Step 3: Repeat the process, until the quotient becomes 1.

**What is the HCF of 27 and 63?**

9

Answer: HCF of 27 and 63 is 9.

## What is the HCF of 9999?

Step-by-step explanation: The factors of 9999 are 1, 3, 9, 11, 33, 99, 101, 303, 909, 1111, 3333, 9999 and the factors of 9433 are 1, 9433. 9999 and 9433 have only one common factor which is 1. This implies that 9999 and 9433 are co-prime. Hence, the Greatest Common Factor (GCF) of 9999 and 9433 is 1.

## How much factors of 10 does the number 1000 have?

We know, the factors of 1000 also divisible by 10 are 10, 20, 40, 50, 100, 200, 250, 500, and 1000. Example 2: What are the total positive pairs of factors of 1000?
