All of them are prime numbers

Out of those numbers, 3 and 5 are prime.

They are: 3 3 and 5

5 is one prime factor of 30 5*3*2=30 All 3 factors are prime numbers.

The GCF of two prime numbers is always 1. 3 and 5 are both prime numbers so, GCF (3, 5) = 1.

3 and 5

3 and 5 are both prime numbers and 1 is their only common factor.

525 = 3 * 5 * 5 * 7

All nonzero numbers have factors. Some factors are prime numbers. 5 is a prime factor of 10.

The prime factors of 15 are 3 and 5 because 3 and 5 are prime numbers that divide evenly into 15. 1 is a factor of 15, but it is not a prime number.

To determine the least common multiple of more than two numbers, determine the prime factors of all numbers. Then, determine the prime factors they have in common with at least one of the other numbers and the ones that are not in common. The prime factor of 2 is 2. The prime factor of 3 is 3. The prime factor of 5 is 5. The prime factors of 9 are 3 and 3. The prime factor 3 is a factor in common in one pair. Multiply all the factors together and divide by any that were in common with the other numbers. Therefore, the least common multiple is 2 x 3 x 5 x 9 ÷ 3 = 90

3, 5, and 7 are all prime numbers so their greatest common factor is 1.

5 is the only prime number in which 5 is a factor.

The prime factors of 75 are 3,5,5 as 3*5*5=75. This can be determined by testing 75 for divisibility by prime numbers starting from 2. Using the prime factorization you can determine that all the factor pairs are (3*5)*5=15*5 and 3*(5*5)=3*25

The prime factors of 150 are 2 x 3 x 5 x 5

You do not. To have a greatest common factor, you need two or more numbers. A common factor is a factor that two or more number have in common. However, the prime factorization of all the numbers will help you find the greatest common factor. The greatest common factor will be the prime factors they have in common multiplied together. Example: The prime factors of 45 are 3, 3, and 5. The prime factors of 60 are 2, 2, 3, and 5. The common prime factors are 3 and 5, so the greatest common factor is 3 x 5 = 15.

One is the common factor because 5 and 3 are both prime numbers.

The first step in answering this problem is to break down 30 into its prime factors. These are 2, 3 and 5. Thus two numbers will have a lowest common multiple of 30 if the only unique prime factors are 2, 3 and 5. In order to have a highest common factor of 3, the two numbers need to have only one shared factor (3). Therefore one of the numbers needs to have the prime factors of 2 and 3, and the other needs to have the prime factors of 3 and 5. Thus, the two numbers with a LCM of 30 and a HCF of 3 are 6 and 15.

5 is one prime factor (all numbers that end with 0 or 5 are divisible by 5). If you divide 91125 by five, you can continue looking for additional prime factors, in the result of the division.

Respectively, they are 3, 7, 5 and 7 but those four numbers do not have a common prime factor.

The prime factor of 25 is 5.

2, 3, 5 are prime numbers but 9 is not a prime number

3 and 5 are both prime and so the prime factorisations are:3 = 3, and 5 = 5.

As a product of its prime factors: 2*3*3*5*5*7 = 3150 or as 2*32*52*7 = 3150
