In Mathematics
277 is the fifty-ninth prime number, following 271 and preceding 281. Its reciprocal has a period of 69, making it the second prime number after 53 with a period of reciprocal one-quarter of the maximum.
277 is the smaller of the two prime factors of the number 9000007 (read nine million and seven), which is significant as the first composite number in the sequence 97, 907, 9007, 90007, 900007, 9000007, 90000007 and so on (the next prime after 900007 has fourteen zeroes).
Since no number added to the sum of its digits generates 277, it is a self number. The next prime self number is not reached until 367.

Famous quotes containing the word mathematics:
“I must study politics and war that my sons may have liberty to study mathematics and philosophy.”
—John Adams (1735–1826)
“Mathematics alone make us feel the limits of our intelligence. For we can always suppose in the case of an experiment that it is inexplicable because we don’t happen to have all the data. In mathematics we have all the data ... and yet we don’t understand. We always come back to the contemplation of our human wretchedness. What force is in relation to our will, the impenetrable opacity of mathematics is in relation to our intelligence.”
—Simone Weil (1909–1943)
