Step-by-step explanation:
the factors of factors are also factors of the main number.
so, 4 = 2×2, 6 = 2×3, that means 2 and 3 are also factors.
and 1 and the number itself are factors too.
so, we have already
1, 2, 3, 4, 6, x
these 6 factors would be the factors for 12 (x = 12).
but we need 8 factors.
so, multiplying the factors from small to bigger to create something we did not have yet, we can add
2×4 = 8 and 3×4 = 12
x = 24
has then 8 factors :
1, 2, 3, 4, 6, 8, 12, 24
