The question does not make sense.
yes
Nun buoys typically have odd numbers. In the IALA buoyage system, odd-numbered nun buoys are used to indicate the right side of a navigable channel when approaching from seaward. They are usually colored red and have a conical shape. Even-numbered buoys, on the other hand, are used for the left side of the channel and are typically green.
Sequential numbers appear sometimes on channel buoys
It is an even number.
An even number can be a multiple of an odd number OR an even number. An odd number cannot be a multiple of an even number.

In U.S. coastal waters, even-numbered nun buoys are colored green. These buoys are typically cone-shaped and are used as navigational aids to indicate the channel's edge and help boaters identify safe passage. They are part of the lateral buoy system, where even-numbered buoys are on the port side when entering from the sea.
In the United States, red buoys have red lights, and are even numbered. If the are unlit they are in the shape of a semi-cone and are called "nun" buoys. The day markers are red triangles.
Red buoys have even numbers and red lights; green buoys have odd numbers and green lights.
A boat should cruise between a green and red buoy. The red buoy will always be located on the right side of your boat. Red buoys will always mean , returning, red, and right. There will be a number on a red buoy that will give the chart location. The numbers will always be even.
Buoys are marked with their location, owner, serial number, and depth. This helps to quickly identify individual buoys and keep track of them.

Lateral red and green buoys and markers are used in maritime navigation to indicate safe channels for vessels. Red buoys, typically marked with an even number, indicate the port side of a channel when entering from the sea, while green buoys, marked with an odd number, indicate the starboard side. This system helps mariners safely navigate through waterways by providing clear visual guidance on channel boundaries. Together, they form part of the IALA (International Association of Lighthouse Authorities) buoyage system.
In coastal waters, cone-shaped even-numbered nun buoys are colored green. These buoys are used to indicate the starboard side of a channel when entering from the sea. They typically have a green color and may feature a reflective surface for visibility at night.
