14 and 2
16 and 3
How about: 4+12 = 16
63? But it has more than two one-digit factors.
1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 256, 448, 512, 896, 1792, 3584
xy = 64 x + y = 16 y = 16-x x(16-x) = 64 16x -x^2 -64 = 0 x^2 -16x + 64 = 0 (x-8)(x-8) =0 both factors = 8
The sum of the factors of 2^16 - 1 = 65535 is 299.
If we multiply the gcd and the LCM, we get the numbers.Call the numbers a and b. So 16(LCM)=ab3584=ab let's all the LCM, x 16x=a(3584/a)using the information above.x= 1/16(3584)or x=224 So the LCM is 224 we can just say the (gcd)LCM=ab=3584, so just divide 3584 by 16.
54 and 16.
13 and 3
16 and 3
How about: 4+12 = 16
7 and 9
7 and 9
24 and 16 are factors of 48
Factors for 16 are: 1, 2, 4, 8, 16 Sum = 1 + 2 + 4 + 8 + 16 = 31
