Download Solution PDFConcept used:
For finding number of factors of any number we do prime factorisation of that number.
If X = p1a × p2b, then
Number of factors of X = (a + 1) × (b + 1)
where, p1, p2 → Prime factors of X
Calculation:
Now, 40 = 23 × 51
⇒ Number of factors of 40 = (3 + 1) × (1 + 1) = 4 × 2 = 8
∴ The number of factors of 40 is 8.
