140, 280, 420 and so on.
20 just do 4 times whatever and 7 times whatever until you get a like answer :)
Because 20 is a multiple of 4. All multiples of 20 are also multipples of 2, 5 and 10
The LCM of 7 and 20 is 140
Multiples of 4: 4, 8, 12, 16, 20 Multiples of 10: 10, 20 Therefore, the answer is 20. (:
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.
the first three common multiples of 7, 20, and 35 are 140, 280, and 420
To find a common multiple for 2, 4, and 7 with a digit sum of 11, we first need to find the multiples of each number. The multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and so on. The multiples of 4 are 4, 8, 12, 16, 20, and so on. The multiples of 7 are 7, 14, 21, 28, 35, and so on. By examining the lists, we find that the number 28 is a common multiple for 2, 4, and 7 with a digit sum of 11.
4, 8, 12, 16, 20, 24, 28
Yes.
The first 5 multiples of 4 and 20 are 20, 40, 60, 80, 100
There are 7 such numbers: 4, 8, 12, 16, 20, 24, 28.
