Its prime factors are 2 and 13
Prime Factors of 676: 1, 2, 13 676 = 2 * 2 * 13 * 13 = 22 * 132
2 x 2 x 13 x 13
2 x 2 x 13 x 13
Since it wold take up a lot of space, not to mention enormous time, to write all of the primes of every number between 1 and 676. I have place a link to a prime factorization tool that will factor all of those numbers. In addition, there is a link that has it all done for you. A table with all the prime factors of the numbers you requested.
13
1, 2, 4, 13, 26, 52, 169, 338, 676
First determine the prime factors. then write in exponent form (power form or index form) thus your answer would be 2^2 x 13^2.
1, 2, 4, 13, 26, 52, 169, 338, 676
676 = 2 x 2 x 13 x 13 or 22 x 132
The positive integer factors of 377 are: 1, 13, 29, 377
The proper factors are 19 and 73 and both of them are prime so that makes them the prime factors as well. A list of all the factors might include 1, 19,73, and 1387
