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.
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.
There are 5 prime numbers from 60 to 80:61, 67, 71, 73 and 79
There are no prime numbers between 70 and 80 because all the numbers in that range have factors other than 1 and themselves. For example, 72 can be divided evenly by 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36, so it is not a prime number. Similarly, all the other numbers between 70 and 80 have multiple factors, making them composite numbers.
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
