Common multiples of 3 and 7 are numbers that are divisible by both 3 and 7. To find the common multiples up to 100, we need to find numbers that are multiples of both 3 and 7. The common multiples of 3 and 7 up to 100 are 21, 42, 63, and 84. These numbers are multiples of both 3 and 7 within the range of 1 to 100.
4,8,12,16,20
All multiples of 7, which is an infinite number.
84, 91 and 98
301, 308, 315, 322, 329, 336, 343, 350, 357, 364, 371, 378, 385, 392, 399.
They are: 7 14 21 28 and 35
28 and 56
Since 14 is a multiple of 7, all of its multiples are common.
60, 120, 180, 240, 300, 360, 420.
They are 7*1 7*2 7*3 all the way to 7*100 Sit down with a calculator and go through.
There are several multiples of 100. The multiples of 1 are: 1, 2, 3, 4, 5, 6, 7, 8 ect. All you have to do is add 2 zeroes. The multiples of 100 are: 100, 200, 300, 400, 500, 600, 700, 800 ect.
Multiples of 28
The first twelve positive integer multiples of 300 are as follows: 1 x 300 = 300 2 x 300 = 600 3 x 300 = 900 4 x 300 = 1200 5 x 300 = 1500 6 x 300 = 1800 7 x 300 = 2100 8 x 300 = 2400 9 x 300 = 2700 10 x 300 = 3000
Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
There are 71 multiples altogether here. Some of them are 7, 14, 21.
42 is the LCM of 3, 6 and 7. All multiples of 42 are multiples of 3, 6 and 7
There are no multiples of 7 down there, nor are there any NON-multiples of 7 . The truth is that there are no numbers at all below.
