The two strands of Decorative light will shine at same time after every 15 seconds.

<h3>What is defined as the Highest common factor?</h3>

The greatest of all their common factors is the Highest Common Factor (HCF) of more than one number.
As a result, it is also known as the greatest common factor (GCF).
There isn't an exact formula for determining the greatest common factor of two numbers.
However, when considering prime factorization, we can write a statement that aids in evaluating the greatest common factor of more than one number.

The stated condition are-

The light strand one change color every 30 seconds.

The light strand second change color every 45 seconds.

Prime factorization of both number are;

30 = 2×3×5

45 = 3×3×5

The numbers with highest power are;

HCF(30, 45) = 3×5 = 15.

Thus, the time after which both the light strands will change colour at the same time is 15 seconds.
