3 x 147 = 441
Edit
That is just one of an infinite number of possible answers to the question:
1+440, 2+439, 3+438 etc
or
1.1+439.9, 1.2+438.9, etc
or
1.01+439.99, 1.02+439.98, etc
or
-1+442, -2+443 etc
or
1*441, 10*44.1, 100*4.41, 1000*0.441, 10000*0.0441 etc
or
441/1, or 4410/10, or 44100/100, etc
and so on and on and on.
And then you could bring in irrationals and then complex numbers.
21 multiplies to 21 to make it 441
2 + 3 + 5 + 431 = 441
21
441 has many more factors than 2. 441 is 21 squared, and it is also 49 times 9. 3 and 7 are factors as well.
3 x 3 x 7 x 7 = 441
You need at least two numbers to find a GCF.
No, prime numbers refer to whole numbers, not decimals.
The numbers are 21 and 24. 576 - 441 = 135
441
It is: 3*3*7*7 = 441
3*3*7*7 = 441
441 divides evenly by these numbers: 1 3 7 9 21 49 63 147 and 441.
