Given numbers are 372,391,391,939
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 372,391,391,939 is 45526476.
Find LCM of 372,391,391,939 with Prime Factorization
| 3 | 372, 391, 391, 939 |
| 17 | 124, 391, 391, 313 |
| 23 | 124, 23, 23, 313 |
| 124, 1, 1, 313 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 23 x 124 x 1 x 1 x 313 = 45526476
Therefore, the lowest common multiple of 372,391,391,939 is 45526476.
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.
372 x 391 x 391 x 939 = 53402556348
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.
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
391 : 1, 17, 23, 391
391 : 1, 17, 23, 391
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 372,391,391,939, is 1.
Now, the common factors can be found like this.
372:2x 2x 3x 31
391:17x 23
391:17x 23
939:3x 313
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17x 23 = 1173
Therefore, the value for common factors is 1173.
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 = 53402556348/(1x1173)
LCM = 53402556348/1173
LCM = 45526476
Thus, we can understand that the LCM of 372,391,391,939 is 45526476.
