There are 3 factor pairs of 63:
(12,1)(6,2)(4,3)
30 has four factor pairs:30,115,210,36,5
To find two numbers that multiply to equal 63, you can use the factor pairs of 63. Some examples are 7 and 9 (since 7 x 9 = 63), or 3 and 21 (since 3 x 21 = 63). Additionally, 1 and 63 also work (1 x 63 = 63). These pairs illustrate the different combinations that can yield the product of 63.
The factor pairs of 21 are:1, 213, 7Therefore, the number 21 has two pairs of positive integer factors.
Six of them.
There are 3 factor pairs of 63:63 = 1 x 6363 = 3 x 2163 = 7 x 9
There are 3 factor pairs of 63: 63 = 1 x 63 63 = 3 x 21 63 = 7 x 9
(1, 63) (3, 21) (7, 9)
There are three factor pairs:63 = 1 x 6363 = 3 x 2163 = 7 x 9
These factor pairs, when multiplied, equal 63: (1, 63) (3, 21) (7, 9)
The factor pairs of 210 are: 1 and 210, 2 and 105, 3 and 70, 5 and 42, 6 and 35, 7 and 30, 10 and 21, and 14 and 15. The factor pairs of 63 are: 1 and 63, 3 and 21, and 7 and 9.
Sixteen factor pairs.
