20 and 40
2, 4, 6
2, 4, 6
Since 4 is a multiple of 2, all the multiples of 4 will be common.
52 and 56 are multiples of 4 and have 1, 2 and 4 in common. 54 and 57 are multiples of 3 and have 1 and 3 in common.
Get the first common multiple, then multiply that by 0, 1, 2, 3, 4, etc. to get additional common multiples.
4, 8 and 12 are the first 3 common multiples of 2 and 4
The first 2 common multiples of 4 and 12 are 12 and 24.
4 is.
60 and its multiples
1
The multiples of 10 are: 1, 2, 5, 10 The multiples of 5 are: 1 and 5. The multiples of 6 are: 1, 2, 3, and 6. The multiples of 8 are: 1, 2, 4, and 8. The number that they all have in common is 1, so the lcd is one.
The Least Common Multiple (LCM) for 2 4 is 4.
