NO!!! Because '222222' will divide by '2' the lowest factor' .Hence

2)222222 = 111111

3)111111 = 37037

7)37037 = 5291

11)5291 = 481

13)381 = 37

37)37 = 1

NB The prime numbers, 2,3,7,11 & 37 have been used once to find the factors of 222222.

NNB Always divide by the prime numbers until it is reduced to '1'.

NNNB '5' as a Prime number, has not been used becaause none of the composite numbers end in '5'.
