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.
The GCF of 15 and 49 is 1. The factors of 15 are 1, 3, 5, and 15 The factors of 49 are 1, 7, and 49 The only common factor is 1, so the greatest common factor of 15 and 49 is 1.
The GCF of 8, 15, and 49 is 1
The GCF is 1.
The numbers 15, 32, and 49 are relatively prime because their greatest common factor is 1.
In each of those cases, the only composite factor of the number is the number itself.
Factor tree for 49:49/ \7 x 7497,7
Factor: 49 = 7(7)
The greatest common factor of 49 and 343 is 49.
49 is.
The factor of both 28 and 49 is 78.
49 is a compound number; it is only divisible by 1 and itself (49). 49 is not a factor of 200. This automatically means that the greatest common factor of 49 and 200 is 1.
The GCF (Greatest Common Factor) of 49 and 343 is 49. Since 49 is a factor of 343, it is automatically the GCF.
