Peterson Number in Java

Java Program to check whether a given number is Peterson or not through a Java program.

Peterson Number

A number is said to be Peterson if the sum of factorials of each digit is equal to the sum of the number itself.

• Suppose, we have to check the number (n) 145 is Peterson or not.

Number = 145

145 = !1 + !4 + !5

=1+4321+5432*1

=1+24+120

145=145

We observe that the number and the sum of factorials of digits are equal to the number itself. Hence, 145 is a Peterson number.
