Given numbers are 270,172,440,328
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 270,172,440,328 is 20944440.
Find LCM of 270,172,440,328 with Prime Factorization
| 2 | 270, 172, 440, 328 |
| 2 | 135, 86, 220, 164 |
| 2 | 135, 43, 110, 82 |
| 5 | 135, 43, 55, 41 |
| 27, 43, 11, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 27 x 43 x 11 x 41 = 20944440
Therefore, the lowest common multiple of 270,172,440,328 is 20944440.
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.
270 x 172 x 440 x 328 = 6702220800
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.
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
172 : 1, 2, 4, 43, 86, 172
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
328 : 1, 2, 4, 8, 41, 82, 164, 328
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 270,172,440,328, is 2.
Now, the common factors can be found like this.
270:2x 3x 3x 3x 5
172:2x 2x 43
440:2x 2x 2x 5x 11
328:2x 2x 2x 41
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 2x 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 6702220800/(2x160)
LCM = 6702220800/320
LCM = 20944440
Thus, we can understand that the LCM of 270,172,440,328 is 20944440.
