1 and 3.
There is no number that goes into both. must be a trick questionthis is another person not the same one :)the number that goes into 12 and 21 is 3 which is a 5th grade problemwho ever said theres no number that goes into 12 and 21 is WRONG!
1, 2, 3, 4, 6, 12
Four goes into both 12 and 4. Four goes into 12 three times, and into 4 once. 12/4 = 3 4/4 = 1
iif a factor is something that goes into a bigger number. a trick is to add up all the digits in this case 9+1+2 and see if 3 goes into that. for this it is 12 and 3 goes into 12 so it also goes into 912. hope this helps :)
1 and 3 I got that by counting by three's 3,6,9,12,15,18.....
1, 2, 3, 4, 6, 12.
