How do you find the unit digit of a number?
To identify the unit digit of a number with some power, we must be aware of cyclicity. Cyclicity of any number is about the last digit and how they appear in a certain defined manner. Let us consider the values of 2n, where n = 1, 2, 3……… We get unit digit 2 in the result of 2n, when n = 1.
What is the unit digit of (3547)153 x (251)72?
Cyclicity of 10 is 1. Find the unit digit in the product : (3547) 153 x (251) 72 In (3547) 153, unit digit is 7. The cyclicity of 7 is 4. Dividing 153 by 4, we get 1 as remainder. So, the unit digit of 7153 is 7. In 251 72, unit digit is 1. Because 1 has the cyclicity 1, the unit digit of 251 72 is 1. (3547)153 x (251)72 is 7.
