There is insufficient information for us to even begin to understand this question. Please edit the question to include more context or relevant information. "both" implies two numbers but you have given only one!
Oh, dude, you want common multiples of 3 and 7 up to 100? Well, let me break it down for you. The common multiples of 3 and 7 are numbers that both 3 and 7 can divide evenly into. So, the common multiples of 3 and 7 up to 100 are 21, 42, 63, and 84. Like, that's it.
There is an infinite amount of common multiples starting with 77.
Multiples of 4 are 4,8,12,16,20,24,28,32... Multiples of 7 are 7,14,21,28,35,42,49,56... The smallest number that is a multiple of both numbers is 28
The common multiples of 4 and 7 are numbers that are divisible by both 4 and 7. To find the common multiples, you can list out the multiples of each number and then identify the numbers that appear in both lists. The common multiples of 4 and 7 are 28, 56, 84, 112, and so on, as they are divisible by both 4 and 7.
Since the lowest common multiple of 6 and 7 is 42, the multiples of 6 and 7 are multiples of 42. The first five are: 42 84 126 168 210
The number of integers that are multiples of both 235 and 7 is infinite. Here are the first few: 1645, 3290, 4935, 6580, 8225 . . .
35 and 70 both have 7 and 5 as prime factors
The number of integers that are multiples of both 20 and 7 is infinite. Here are the first few: 140, 280, 420, 560, 700, 840 . . .
Odd multiples of 7 less than 50 are numbers that are both odd and divisible by 7, and are less than 50. The odd multiples of 7 less than 50 are 7, 21, and 35. These numbers are odd because they are not divisible by 2, and they are multiples of 7 because they can be divided evenly by 7.
11,22,33,44,55,66,77,88,99 7,14,21,28,35,42,56,63,70
105 is the lowest, following this, multiples of 105
35 because 5x7 is 35 so that is a multiple of BOTH and 45
