if the ones digit of a number greater than 1 is 0, what factor or factors must that number have?
a-2 only
b-5 only
c-2 and 5
d-neither 2 or 5
two and five will go into 20, 40, 60, ...
2 and 5
What is it
To determine the factor or factors of a number with a ones digit of 0, we need to consider the prime factors of that number. The prime factors of a number are the smallest prime numbers that divide evenly into it.
In this case, since the ones digit is 0, the number is divisible by 10. The prime factors of 10 are 2 and 5.
Therefore, the correct answer is (c) 2 and 5.
