Given numbers are 350,478,380,440,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 350,478,380,440,405 is 5664443400.
Find LCM of 350,478,380,440,405 with Prime Factorization
| 2 | 350, 478, 380, 440, 405 |
| 2 | 175, 239, 190, 220, 405 |
| 5 | 175, 239, 95, 110, 405 |
| 35, 239, 19, 22, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 35 x 239 x 19 x 22 x 81 = 5664443400
Therefore, the lowest common multiple of 350,478,380,440,405 is 5664443400.
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.
350 x 478 x 380 x 440 x 405 = 11328886800000
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.
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
478 : 1, 2, 239, 478
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 350,478,380,440,405, is 1.
Now, the common factors can be found like this.
350:2x 5x 5x 7
478:2x 239
380:2x 2x 5x 19
440:2x 2x 2x 5x 11
405:3x 3x 3x 3x 5
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 5x 5x 5 = 2000
Therefore, the value for common factors is 2000.
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 = 11328886800000/(1x2000)
LCM = 11328886800000/2000
LCM = 5664443400
Thus, we can understand that the LCM of 350,478,380,440,405 is 5664443400.
