Given numbers are 638,363,753,934
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,363,753,934 is 2467886718.
Find LCM of 638,363,753,934 with Prime Factorization
| 2 | 638, 363, 753, 934 |
| 3 | 319, 363, 753, 467 |
| 11 | 319, 121, 251, 467 |
| 29, 11, 251, 467 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 29 x 11 x 251 x 467 = 2467886718
Therefore, the lowest common multiple of 638,363,753,934 is 2467886718.
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.
638 x 363 x 753 x 934 = 162880523388
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
363 : 1, 3, 11, 33, 121, 363
753 : 1, 3, 251, 753
934 : 1, 2, 467, 934
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,363,753,934, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
363:3x 11x 11
753:3x 251
934:2x 467
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 162880523388/(1x66)
LCM = 162880523388/66
LCM = 2467886718
Thus, we can understand that the LCM of 638,363,753,934 is 2467886718.
