They are members of the infinite set of numbers of the form 21*k where k is an integer.
1, 21, 3, 7 are divisible by 21 :)
1, 3, 7, 21
Some numbers that are divisible by 63 is 1,3,7,9, and 21.
Because 21 is divisible by numbers other than 1 and 21. 21 is divisible by 1, 3, 7, 21
How many numbers less than 700 are divisible by both 15 and 21?
No.
Since the numbers are coprime, the answer is 21*13 = 273.
Some numbers that are divisible by 63 is 1,3,7,9, and 21.
The numbers 21 and 126 are divisible by seven. The numbers 88 and 255 have a remainder when divided, so they are not divisible by seven.

No.
There are no numbers that are divisible by 21 but not by 7 so the "or 21" part of the question can be ignored.There are 166 numbers between 1 and 1000 that are divisible by 6. However, 23 of those are also divisible by 7.So 166 - 23 = 143 numbers.
Any multiple of 21
Since the numbers are coprime, the answer is 21*13 = 273.
Yes it's 21 All even numbers are divisible by two.
