UNITS DIGIT OF ANY INTEGER Hi peeps, While preparing I noticed this and thought it will be useful to all. Not sure if someone has already posted it.
For instance what is the units digit of 567^996? The unit digit depends only on the unit digit of the original number. here "7". Refer the table below: As 996 is a multiple of 4, we ca find that the unit digit of 567^996 is 1.
UNITS DIGIT OF ANY INTEGER with INTEGER POWERS (1,2,3...)
1 = Always 1 2 = 2, 4, 8, 6 repeats 3 = 3, 9, 7, 1 repeats 4 = 4 , 6 repeats 5 = Always 5 6 = Always 6 7 = 7, 9, 3, 1 repeats 8 = 8, 4, 2, 6 repeats 9 = 9, 1 repeats 10 = always 0
