4 (5 if you count 1).
Yes, because 1 and 5 are odd number and the factors of 10 are 1, 2, 5, and 10.
A whole number has an odd number of unique factors if and only if it is a perfect square. The perfect squares less than 10 are 0, 1, 4, and 9. Therefore, there are four whole numbers less than 10 that have an odd number of unique factors.
50 has six factors: 1, 2, 5, 10, 25 and 50. Odd factors are 1, 5 and 25. Fraction for the odd factors is 3/6 or 1/2. So it means 1/2 of factors of 50 are odd factors.
1 000 000/100 000 = 10 Answer: 10
The factors of 20 are 1,2,4,5,10 and 20. Two are odd, four are even.
10
10 000 of them.
1 000 000 = 10 000 x 100 so therefore there are 10 000 zeros in 1 000 000
1 000 000 / 100 = 10 000
Just 25.
50 000/5 = 10 000 10 000 times.
The positive integer factors of 30 are: 1 2 3 5 6 10 15 30 The odd factors are therefore 1, 3, 5, 15
