Yes by all
1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
No. (Example.....10 / 2 = 5, but 10 / 4 = 2.5)
650130 is not divisible by 4, but it is divisible by 2, 3, 5, 6, and 10
From that list, 20 is divisible by 2, 4, 5 and 10.
Out of that list, 2, 4, 5 and 10.
Its divisible by 2 and 4.
9 is divisible by 3 10 is divisible by 2, 5 and 10. Everything else, no.
The factors of 320 are: 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
160 is even so it's divisible by 2 160/2=80.....so far we have a 2 80 is even again, 80/2=40 now we have 2^2 40/2 = 20 we have 2^3 20/2 = 10 ...2^4 10/2= 5 ... 2^5 5 is prime so the prime factorization of 160 is 2^5 *5
The number 44 is divisible by: 2 - 44/2 = 22 4 - 44/4 = 11 The number is not divisible by 3, 5, 6, or 10.
No since only numbers in which its sum can be divisible by 3 is divisible by 3. 2 + 4 + 4 is 10, and 10 is not divisible by 3.
Out of that list, 40 is divisible by 2, 4, 5, 8 and 10.
