The factors of 10 are 1, 2, 5 and 10. You need at least two numbers to find a GCF.
The factors of 10 are 1,2,5,10.
There are four factors of 10: 1, 2, 5 and 10.
The factors of 10 are 1, 2, 5 and 10. For them to be common, they need to be compared to another set of factors.
The factors of 8 are: 1, 2, 4, 8 The factors of 10 are: 1, 2, 5, 10
4 (5 if you count 1).
[I'll assume 30 billion to mean 30 000 000 000, although some would consider it to denote 30 000 000 000 000.] Start with the prime factorisation of 30 000 000 000. 30 000 000 000 = 3 x 1010 = 3 x (2 x 5)10 = 210 x 3 x 510 The factors of 30 billion can be counted using this prime factorisation. First there are the factors of the form 2n, 3n or 5n. For 2 and 5, n varies between 1 and 10. 10 + 10 + 1 = 21 Then there are ten ways of multiplying 3 with 2n, ten more of multiplying 3 with 5n, and 100 ways of multiplying 2n with 3n. 10 + 10 + 100 = 120 Finally, there are 100 ways of multiplying 2n x 3 x 5n, one of which is 30 billion itself. We might also include, trivially, 1. 100 + 1 = 101. That leaves us with 101 + 120 + 21 = 242 factors, including one and 30 billion itself.
10 000 000 = 10 to the power of 7
It is 100.
-8
53
100, 000, 000 * 10, 000 = 1, 000, 000, 000
Next power of 10 after 10 000 is 100 000.
I'm guessing that is: (70 000 000)² = (7×10^7)^2 = (7×10^7) × (7×10^7) = (7×7)×(10^7 × 10^7) = (7×7)×10^(7+7) = 49×10^14 = 4 900 000 000 000 000
1 billionth = 10-9 (1 billionth)4 = (10-9)4 = 10-36 That's 0.000 000 000 000 000 000 000 000 000 000 000 001
If you mean as in scientific notation then it is: 1.0*10^16
2.3*10^10
