7x2x3x2x2x5=840
7*5*4*3*2 Is the longest factor string of 840
840 = 23 x 31 x 51 x 71
840 = 2 x 2 x 2 x 3 x 5 x 7
2 x 2 x 2 x 3 x 5 x 7
2 x 2 x 2 x 3 x 5 x 7
2 x 2 x 2 x 3 x 5 x 7 = 840
Find one factor, divide by it to get the other factor. Continue separating each of the factors into smaller factors, until you only have prime numbers. For example, 840 = 2 x 420. Now continue finding smaller factors for 420.
