The factors of 49 are: 1 7 49
Factors of 49: 1, 7, 49 Factors of 29: 1, 29
The factors of 49 are 1, 7, and 49.
No, the only factors of 49 are 1, 7, and 49. Therefore, 8 and 5 are not factors of 49.
The factors of 31 are: 1, 31 The factors of 49 are: 1, 7, 49
To determine if 15 is a multiple of 49, determine what the multiples of 15 are. If one of them is 49 then 49 is a multiple of 15. For example, 15, 30. 45, 60. Since 49 is not a multiple of 15, 15 is not a factor of 49.
