21
Any number can be multiplied to get the answer 441. For example 5 can be multiplied by 88.2 If the question was which number can be multiplied by itself, the answers are: -21 and +21
It is: 21*21 = 441
3*3*7*7 = 441
As a product of its prime factors: 3*3*7*7 = 441
To find four numbers that multiply together to give 441, one possible combination is 3, 7, 3, and 7. This works because 3 × 7 = 21, and multiplying 21 by 3 and 7 again (21 × 3 × 7) results in 441. Alternatively, you could also use 1, 3, 7, and 21, as 1 × 3 × 7 × 21 also equals 441.

21 multiplies to 21 to make it 441
It is: 21*21 = 441
3 x 3 x 7 x 7 = 441
3*3*7*7 = 441
3 x 3 x 7 x 7 = 441
