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 first 3 multiples of 7 are: 7, 14, and 21.
42 is the LCM of 3, 6 and 7. All multiples of 42 are multiples of 3, 6 and 7
Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
The common multiples of 3 and 7 are 21, 42, 63 and so on.
The LCM of 3 and 7 is 21
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.
Odd multiples of 21.
The multiples of 2, 3 and 7 is 42.
21,42 and 63 are the first three multiples
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.
