Answer 2

$*Question:-$

write the smallest 4 digit number using different digits and also find its prime factorisation.

$*Answer:-$

1000 is the smallest 4 digit number.

We know that,

→ 1000 = 2 × 500

= 2 × 2 × 250

So we get ,

• → 1000 = 2 × 2 × 2 × 125

It can be further expanded as,

• → 1000 = 2 × 2 × 2 × 5 × 25

We get ,

• → 1000 = 2 × 2 × 2 × 5 × 5 × 5

Therefore the smallest 4 digit number is 1000 and can be expressed as 2 × 2 × 2 × 5 × 5 × 5 .
