Question

Find all the integer factors of 245 .

Answer 1

First get the prime factorization

Answer 2

So \(245=5\times 7\times 7\).

Answer 3

All numbers have the factor \(1\).
Selecting single factors, we get \(5\) and \(7\).
Selecting pairs of factors, we get \(5\times7=35\) and \(7\times7=49\).
Selecting all three numbers, we get \(5\times7\times7=245\).

Answer 4

so All factors of 245 is 1, 5, 7, 35, 49, 245

Answer 5

yes
