1 and 5.
There are three: 1, 5 and 25.
It depends on (a) the first five numbers of what and(b) what sort of sequence.ANY 5 numbers can be put into a quartic sequence. So the answer is: every time.
They are: 3, 5 and 7
Of the first 5 prime numbers, 3, 5 and 7 are factors of 2625.
The sum of the first 5 numbers is 15. 1+2+3+4+5=15
As a product of its prime numbers: 5*5*5 = 125
The numbers that go into 45 are 1, 5, 9, 45
only 1 and 5 can go into 5
1 and 5 are the only numbers.
The numbers that go into 35 are 1, 5, 7,and 35
The only number that can go into both numbers is 5
