225 has five factor pairs:225,175,345,525,915,15
The factor pairs of 51 are (1,51) and (17,3)
The difference is between factor pairs and distinct factors. With square numbers, one of the factor pairs will be the same number twice. When listing the distinct factors, that number is only listed once.
The factor pairs of 98 are (1,98), (2,49), and (7,14).
One pair: it's a prime number.
1 and 5
Five of them.
5 and 1
225 has five factor pairs:225,175,345,525,915,15
Five pairs. (80,1)(40,2)(20,4)(16,5)(10,8)
Yes. Factor pairs are always repeated across pairs since factor pairs are certain kinds of pairs.
There are really only three distinct factor pairs:(16, 1) (8, 2)(4, 4)I suppose if you count (1,16) and (2,8) as being different from (16, 1) and (8,2), you could end up with as many as five factor pairs.
There are five factor pairs for 196:196 = 1 x 196196 = 2 x 98196 = 4 x 49196 = 7 x 28196 = 14 x 14
the factor pairs are 1x35 & 5x7
The factor pairs of 28 are :28,114,27,4
Sixteen factor pairs.
The five factor pairs of 80 are:80 = 1 x 8080 = 2 x 4080 = 4 x 2080 = 5 x 1680 = 8 x 10
