The factors of 16 are: 1, 2, 4, 8, 16 The factors of 52 are: 1, 2, 4, 13, 26, 52
The factors of 13 are 1 and 13. The factors of 16 are 1, 2, 4, 8, and 16. The only common factor is 1. Therefore, 1 is the greatest common factor. This means 13 and 16 are relatively prime. 1, in whole numbers.
13 times 16 is 208, and 16 times 13 is 208. Since 13 is prime and not a factor of 16, 13 and 16 have no common factors other than 1. Therefore, 208 is the lowest common multiple of 13 and 16.
The factors of 13 are: 1, 13The factors of 16 are: 1, 2, 4, 8, 16The common factors are: 1The Greatest Common Factor (GCF) is: 1
