CXLVII

CXLVII is the Roman numeral representation of the integer 147. In Roman numerals, C stands for 100, XL stands for 40, and VII stands for 7; together they sum to 147.

Numerically, 147 is a composite number. Its prime factorization is 3 multiplied by 7 squared (3 × 7^2). Its positive divisors are 1, 3, 7, 21, 49, and 147, giving it six divisors in total. The digit sum is 12. It is not a prime, and it is not a simple power of a prime beyond its square factor.

CXLVII is used in contexts where Roman numerals denote order or dating. It can designate the 147th item in a sequence, such as a chapter, section, or list, or it can appear as a year in historical dating, for example as 147 CE (Anno Domini) or 147 BCE, depending on the era being referenced. In modern writing and cataloging, Roman numerals like CXLVII are often employed for numbering chapters, monarchs, events, or designations in formal or stylistic contexts.

Historically, the value and structure of CXLVII reflect the broader Roman numeral system, which uses combinations of letters to indicate additive and subtractive values. While its practical significance is largely contextual, CXLVII remains a standard representation for the number 147 in records, monuments, and textual traditions that use Roman numerals.
