1, 2, 4, 5, 8, 10, 16, 20, 40, 80
The prime numbers (factors) of 80 are: 2 and 5
They are the numbers that have more than two factors in them.
Itself and any of its factors
ANSWER: 70 and 80 are not prime numbers. They are composite numbers:70 is a composite number because the factors of 70 other 1 and itself (70) are 2, 5, 7, 10, 14, and 35.80 is also a composite number because the factors of 80 other 1 and itself (80) are 2, 4, 5, 8, 10,16, 20, and 40.
To determine what goes into both 15 and 80, we need to find their common factors. The factors of 15 are 1, 3, 5, and 15, while the factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The only common factor between the two numbers is 1 and 5. Therefore, the numbers that go into both 15 and 80 are 1 and 5.
Two of the factors of 80 are prime numbers: 2 and 5.
The prime numbers (factors) of 80 are: 2 and 5
All numbers have factors.
The factors of 32: 1,2,5,8,10,16,20,32 The factors of 80: 1,2,4,5,8,10,16,20,40 The GCF (greatest common factor) of the numbers is 16!!
Because both numbers are factors of 80.
They are 2 and 5
A number will always have 1 and itself as factors. And thus the only numbers with 2 factors will be prime numbers. The only prime numbers below 20 are 2, 3, 5, 7, 11, 13, 17 and 19, and thus these are the only numbers below 20 that have 2 factors.
They are the numbers that have more than two factors in them.
Yes and by any of its factors
To find two factors of 80 that add up to -2, we need to look for pairs of numbers whose product is 80 and whose sum is -2. The factors that satisfy this condition are -10 and 8, since (-10) + 8 = -2 and (-10) * 8 = -80. Thus, the numbers -10 and 8 are the factors of 80 that add to -2.
48 does.
80 = 2 x 2 x 2 x 2 x 5
