How do I change the trusted phone number for my apple Id? I do not have that phone number anymore

You need to change/add the number on your Apple ID. Look in the Security section when signed in online. You may have to add the new number before you can remove the old number. After the change, allow up to 24 hours for the change to sync. Before trying to make the change, sign out of Messages/FaceTime on all devices/computers.

Apple ID - Manage

See the following from Two-factor authentication for Apple ID - Apple Support

You can manage your trusted phone numbers, trusted devices, and other account information from your Apple ID account page.
