1 x 125, 5 x 25, 25 x 5, 125 x 1
1 x 250, 2 x 125, 5 x 50, 10 x 25 and 125 + 125 = 250
1 x 125, 5 x 25
Expanded Notation of 125 = (1 x 100) + (2 x 10) + (5 x 1)
First 125 numbers sum to 125/2 x 126, so first 125 even numbers sum to double that ie 125 x 126 = 15750
72 = 2 x 2 x 2 x 3 x 3 125 = 5 x 5 x 5 Accordingly, The greatest common factor is: 72 x 125 = 9000
1 x 125, 5 x 25, 25 x 5, 125 x 1
1 x 250, 2 x 125, 5 x 50, 10 x 25 and 125 + 125 = 250
1 x 125, 5 x 25
Expanded Notation of 125 = (1 x 100) + (2 x 10) + (5 x 1)
First 125 numbers sum to 125/2 x 126, so first 125 even numbers sum to double that ie 125 x 126 = 15750

(x + 5)(x^2 - 5x + 25)
1 x 250, 2 x 125, 5 x 50, 10 x 25, 25 x 10, 50 x 5, 125 x 2, 250 x 1 = 250
If 2x2 = 250 then x2 = 250/2 = 125 So x = sqrt(125) = 5*sqrt(5) = +/- 5*2.236 = + or - 11.180
125 x 2
Fifty 125 / 5 = 25 25 x 2 = 50
