Answer:
4!
Step-by-step explanation:
Given four numbers 2, 4, 6, 8.
The numbers can be arranged to form an odd number which is less than 300.
That means we have three spaces to fill this. We can try out the different combination of the numbers.
Note that the numbers should be odd. So, in the unit digit should only be 5. 2, 4, 8 would make the number even.
Also, the first digit can only be two because other numbers would make it bigger than 300.
So, 2 ___ 5 is fixed. The middle digit could be any of the four.
So, 225; 245; 255 and 285 all satisfy the conditions.
So, four numbers can be formed.

This sequence has properties similar to those of the Fibonacci sequence.
Answer:
The GCF is going to be 30
Step-by-step explanation:
This Is how I find the GCF of 2 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here
The prime factorization of 21, 2 × 3 × 3 × 5= 90
The prime factorization of 28, 2 × 3 × 5 × 7 = 210
The common factors are, 2, 3, and 5. We multiply those to get the GCF.
2 × 3 × 5 = 30
