Common multiples of 2, 3, and 7 are numbers that are divisible by all three numbers. To find the common multiples, we first list the multiples of each number: multiples of 2 are 2, 4, 6, 8, 10, multiples of 3 are 3, 6, 9, 12, 15, and multiples of 7 are 7, 14, 21, 28. The common multiples of 2, 3, and 7 are numbers that appear in all three lists, which in this case are 42, 84, 126, etc.
Well hello there, friend! Let's think about this together. Common multiples are numbers that both 2, 3, and 7 can be divided evenly by. So, if we start by listing out the multiples of each number - 2, 4, 6, 8, 10, 12... 3, 6, 9, 12, 15, 18... 7, 14, 21, 28, 35... - we can see that the common multiples of 2, 3, and 7 are numbers like 42, 84, 126, and so on. Just like painting a happy little tree, finding common multiples can be a peaceful and rewarding process.
To find the common multiples of 2, 3, and 7, we first list the multiples of each number: Multiples of 2: 2, 4, 6, 8, 10, 12, ... Multiples of 3: 3, 6, 9, 12, 15, 18, ... Multiples of 7: 7, 14, 21, 28, 35, ... The first common multiple of 2, 3, and 7 is 6, as it is the smallest number that is a multiple of all three numbers. The second common multiple is 12, as it is the next number that is a multiple of all three numbers.
The common multiples of 2 and 7 are 14, 28, 42, 56, 70, 84, 98, and so on.
The first common multiple of 3 4 5 and 7 is 420.
Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the highest amount of each factor. 2 x 3 x 5 x 7 = 210, the LCM Multiples of 210 will all be common multiples of 30 and 42 and can be found by multiplying 210 by successive counting numbers. 210 x 1 = 210 210 x 2 = 420 210 x 3 = 630 and so on.
The Least Common Multiple (LCM) of (3,7) is 21.
2
lcm(2, 7) = 14 → first 3 common multiples are: 14, 28, 42; lcm(2, 8) = 8 → first 3 common multiples are: 8, 16, 24; lcm(7, 8) = 56 → first 3 common multiples are: 56, 112, 168; lcm(2, 7, 8) = 56 → first 3 common multiples are: 56, 112, 168.
14 = 2 X 7 42 = 2 X 3 X 7 So 2 & 7 are common to both multiples / NB '3' is NOT a common multiple.
To find the common multiples of 2, 3, and 7, we first list the multiples of each number: Multiples of 2: 2, 4, 6, 8, 10, 12, ... Multiples of 3: 3, 6, 9, 12, 15, 18, ... Multiples of 7: 7, 14, 21, 28, 35, ... The first common multiple of 2, 3, and 7 is 6, as it is the smallest number that is a multiple of all three numbers. The second common multiple is 12, as it is the next number that is a multiple of all three numbers.
The common multiples of 3 and 7 are 21, 42, 63 and so on.
42 is the LCM of 3, 6 and 7. All multiples of 42 are multiples of 3, 6 and 7
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
Odd multiples of 21.
There are infinitely many common multiples of 3, 5 and 7, each one 105 larger than the previous one. Or to put it another way: the common multiples of 3, 5 and 7 are the multiples of their lowest common multiple which is 105. ie their common multiples are all the multiples of 105, of which there is no end - there is an infinite number of multiples of 105 (or any other number [except zero]).
You multiply 6, 7, and 8 until all answers are the same. For example, the common multiples of 3 and 7 would be 21, because: 3,6,9,12,15,18,21 7,14,21 See how they both have the common multiples? Hope this helped!
Multiples of 3 are 3, 6, 9 and so on. Multiples of 7 are 7, 14, 21 and so on. The common multiples of 3 and 7 include 21, 42, 63 and so on.
The common multiples of 2 and 7 are 14, 28, 42, 56, 70, 84, 98, and so on.
