Which number is a Fibonacci number hershad number and a motzkin number?

The number 1 is a Fibonacci number, a Harshad number, and a Motzkin number. Fibonacci numbers are generated by the sequence starting with 0 and 1, where each subsequent number is the sum of the two preceding ones. A Harshad number is an integer that is divisible by the sum of its digits, and 1 meets this criterion. Additionally, Motzkin numbers count certain combinatorial structures and include 1 as the first member of the sequence.
