The smallest three-digit multiple of 60 is 120, which ends in 0.

The Smallest Three-Digit Multiple of 60 is 120 — Why It Ends in 0

When exploring the world of numbers, multiples often reveal interesting patterns. One fascinating fact is that 120 is the smallest three-digit multiple of 60 — and it also ends in a 0, showcasing a cool connection between multiples and divisibility rules.

What Is a Multiple of 60?

Understanding the Context

A multiple of 60 is any whole number you get by multiplying 60 by an integer. For example:

60 × 1 = 60 (a two-digit number)
60 × 2 = 120 (a three-digit number)
60 × 3 = 180
and so on.

Thus, 120 is the first three-digit number in the sequence of 60’s multiples.

Why Does Every Multiple of 60 End in 0?

The smallest three-digit multiple of 60 is 120, which ends in 0.

Key Insights

60 is a number with 2 × 2 × 3 × 5 as its prime factorization — notably, it includes both 2 and 5. Together, 2 and 5 form the factor 10, which means every multiple of 60 naturally ends in a zero. This is a general rule: any multiple of 10 ends in 0, and since 60 is a multiple of 10, all its multiples share this trailing zero.

This ties directly to divisibility:

Since 60 = 6 × 10, it’s inherently divisible by 10.
Therefore, 120 ends in 0 because it’s 60 × 2, and multiplying any multiple of 10 by any integer preserves the trailing zero.

The Importance of 120 as the Smallest Three-Digit Multiple

Beyond its numerical value, 120 is significant in real-world contexts. For example:
