An easy way to figure out many of them would to be to multiply 8x5(40). Now, any numbers that are multiples of 40, such as 40,80,120,160, would all have the factors of 8 and 5.
Factors don't have numbers. Numbers have factors. Numbers that have the factors 2, 4 and 8 are 8 and all of its multiples.
The prime numbers (factors) of 75 are: 3 and 5
The factors of 25 are: 1, 5, 25 The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40 The factors of 95 are: 1, 5, 19, 95
The GCF of 5 and 8 is 1. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 5 are 1 and 5. The factors of 8 are 1, 2, 4, and 8 The only common factor is 1. Therefore, the greatest common factor is 1.
The product of all factors of the two numbers is 2097152.
The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.
I could tell you what all the factors of each of those 4 numbers are, but I am guessing you are asking for the common factors. Lets start with the prime factorization of each number: 10 is 2 * 5 8 is 23 12 is 22 * 3 15 is 3 * 5 So no prime factor is common to all 4 numbers. The only common factor is 1.
All numbers have factors. 1, 2, 4 and 8 are factors of 8.
All numbers have factors. Some numbers have some of the same factors as other numbers. Multiples of numbers have all of the factors of numbers that are factors of them, plus some of their own. 32 is a multiple of 16 and will have all of its factors. 64 is a multiple of both 32 and 16 and will have all of their factors.
Called 'factors', the whole numbers that go into 40 evenly are: 1, 2, 4, 5, 8, 10, 20, 40.
All the multiples of 8 including itself
Factors are numbers you can multiply together to get another number. 16: 1, 2, 4, 8, 16 16 has 5 factors.
