3 x 5 x 7
3 x 5 x 7 = 105
315
3*5*7 = 105
The answer is 105 because 3,5, and 7 are all prime factors and when you multiply the numbers together it comes out to be 105 witch is lower than 160 and is an odd number.
For 60, 2, 3 and 5 For 105, 3, 5 and 7
They are: 3*5*7 = 105

To find the greatest common factor of two numbers, you first need to break those numbers down into their prime factors. For 105 and 147 this is: 105 = 3x5x7 147 = 3x7x7 The next step is to identify any common prime factors. In this case, both numbers have a 3 as a prime factor, and a 7 as a prime factor. Multiply these together to get the GCF: 3x7 = 21 Thus the greatest common factor of 105 and 147 is 21.
