Given numbers are 408,205,620,215,567
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,205,620,215,567 is 21072010680.
Find LCM of 408,205,620,215,567 with Prime Factorization
| 2 | 408, 205, 620, 215, 567 |
| 2 | 204, 205, 310, 215, 567 |
| 3 | 102, 205, 155, 215, 567 |
| 5 | 34, 205, 155, 215, 189 |
| 34, 41, 31, 43, 189 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 34 x 41 x 31 x 43 x 189 = 21072010680
Therefore, the lowest common multiple of 408,205,620,215,567 is 21072010680.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
408 x 205 x 620 x 215 x 567 = 6321603204000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
205 : 1, 5, 41, 205
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
215 : 1, 5, 43, 215
567 : 1, 3, 7, 9, 21, 27, 63, 81, 189, 567
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,205,620,215,567, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
205:5x 41
620:2x 2x 5x 31
215:5x 43
567:3x 3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 5x 5 = 300
Therefore, the value for common factors is 300.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 6321603204000/(1x300)
LCM = 6321603204000/300
LCM = 21072010680
Thus, we can understand that the LCM of 408,205,620,215,567 is 21072010680.
