Given numbers are 381,923,533,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,923,533,315 is 1513909215.
Find LCM of 381,923,533,315 with Prime Factorization
| 3 | 381, 923, 533, 315 |
| 13 | 127, 923, 533, 105 |
| 127, 71, 41, 105 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 127 x 71 x 41 x 105 = 1513909215
Therefore, the lowest common multiple of 381,923,533,315 is 1513909215.
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.
381 x 923 x 533 x 315 = 59042459385
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.
381 : 1, 3, 127, 381
923 : 1, 13, 71, 923
533 : 1, 13, 41, 533
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,923,533,315, is 1.
Now, the common factors can be found like this.
381:3x 127
923:13x 71
533:13x 41
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 59042459385/(1x39)
LCM = 59042459385/39
LCM = 1513909215
Thus, we can understand that the LCM of 381,923,533,315 is 1513909215.
