They are called "thousands".
A group of three digits separated by commas in a multidigit number is typically referred to as a "thousands separator." This format is used to enhance readability by breaking large numbers into manageable parts, such as 1,000 or 1,000,000. The commas indicate the transition between thousands, millions, and so on, helping to distinguish the value of each segment.
In place value, a period is each group of three digits separated by commas in a multidigit number.
a decimal in which a digit or group of digits repeats without end
Because it is relatively easy to divide the number into a group of 1 and 3. Much harder to do that with a 16-digit number!

ThreeThe key to answering this question is knowing what the mathematical term "period" means.Period: a period is each group of digits separated by commas in a multidigit number.Example: 30,149,258 is an 8 digit number so each part of the number separated by a comma is 1 period. {30}{149}{258}I hope this helped.
Postcodes in the UK are composed of two groups of letters and numbers, separated by a space.The first group starts with a one- or two-letter prefix, followed by a one- or two-digit number, or one digit and a letter.The second group is always one digit and two letters.Examples:A9 9AAA9A 9AAA99 9AAAA9 9AAAA9A 9AAAA99 9AAA postcode typically covers a business, a P.O. box or group of boxes, or a portion of a residential street.

For the group of 3 digit numbers : Any number from 1-9 can be the 1st digit, any number from 0-9 can be the 2nd digit, the 3rd digit can only be one number that matches the 1st digit. The number of possibilities is thus, 9 x 10 x 1 = 90. For the group of 4 digits : Any number from 1-9 can be the 1st digit, any number from 0-9 can be the second digit, the 3rd digit can only be the one number that matches the 2nd number, and the 4th digit can only be the one number that matches the 1st digit. Number of possibilities is 9 x 10 x 1 x 1 = 90. Giving a total of 180 palindromic numbers between 100 and 10000.
A 12-digit number is called a trillion. In the International System of Numeration, each group of three digits is named based on powers of a thousand. Therefore, a 12-digit number would represent a quantity in the trillions.
