1, 3, 5, 7, 15, 21, 35, 105.
1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315.
The greatest common factor (GCF, not GFC) of 315, 105 and 21 can be calculated by writing down each number's factors. The factorization for the given numbers is: 315 = 3 x 3 x 5 x 7 105 = 3 x 5 x 7 21 = 3 x 7 The common factors are 3 x 7 = 21, so the GCF of 315, 105 and 21 is 21.
Since 315 is a factor of 3150, it is automatically the GCF.
315 has factors 3,3.5,7. 356 has factors of 2,2,89. There are no common factors between these two numbers , except '1'.
The factors of 315 are: 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
The factors of 315 are 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, and 315.
The greatest common factor of 315 , 525 = 105
315
The gcf is 105
The Least Common Multiple (LCM) of 45 and 105 is 315.
Multiples of 105 include 105, 210, 315 and so on. For them to be common, they need to be compared to another set of multiples.
The positive integer factors of 315 are 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, and 315 315 = 1 x 315, 3 x 105, 5 x 63, 7 x 45, 9 x 35, 15 x 21
