Given numbers are 319,414,989,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,414,989,391 is 96540246.
Find LCM of 319,414,989,391 with Prime Factorization
| 23 | 319, 414, 989, 391 |
| 319, 18, 43, 17 |
Multiply the prime numbers at the bottom and the left side.
23 x 319 x 18 x 43 x 17 = 96540246
Therefore, the lowest common multiple of 319,414,989,391 is 96540246.
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.
319 x 414 x 989 x 391 = 51069790134
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.
319 : 1, 11, 29, 319
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
989 : 1, 23, 43, 989
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,414,989,391, is 1.
Now, the common factors can be found like this.
319:11x 29
414:2x 3x 3x 23
989:23x 43
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 23 = 529
Therefore, the value for common factors is 529.
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 = 51069790134/(1x529)
LCM = 51069790134/529
LCM = 96540246
Thus, we can understand that the LCM of 319,414,989,391 is 96540246.
