n = 5
625 x 4 = 2500
1 x 625, 5 x 125, 25 x 25, 125 x 5, 625 x 1 = 625
You want the 'square root (625) = 25 . So 25 x 25 = 25^2 = 625 Without a calculate, we note that '625' ends in '5'.; so it will divide by '5' Hence 5)625= 5)125= ( continue dividing by '5' to reach an answer of '1' ). 5)25= 5)5 = 1 We note that we have divided four times over. 5 x 5 x 5 x 5 This equals 25 x 25 . Hence the number 25 multiplied to itself gives an aanswer of '625'.
Identify the prime factors of 625 which are : 5 x 5 x 5 x 5 = 625. The factors of 625 are therefore 1 x 625, 5 x 125 and 25 x 25. As the number 25 is effectively duplicated then 625 has 5 factors (1, 5, 25, 125 & 625)
5 x 5 x 5 x 5 = 625
25 x 25 = 625
(6 x 100) + (2 x 10) + (5 x 1) = 625
625 x 4 = 2500
1 x 625, 5 x 125, 25 x 25, 125 x 5, 625 x 1 = 625
