Given numbers are 643,957,319,934
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,957,319,934 is 574737834.
Find LCM of 643,957,319,934 with Prime Factorization
| 11 | 643, 957, 319, 934 |
| 29 | 643, 87, 29, 934 |
| 643, 3, 1, 934 |
Multiply the prime numbers at the bottom and the left side.
11 x 29 x 643 x 3 x 1 x 934 = 574737834
Therefore, the lowest common multiple of 643,957,319,934 is 574737834.
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.
643 x 957 x 319 x 934 = 183341369046
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.
643 : 1, 643
957 : 1, 3, 11, 29, 33, 87, 319, 957
319 : 1, 11, 29, 319
934 : 1, 2, 467, 934
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,957,319,934, is 1.
Now, the common factors can be found like this.
643:643
957:3x 11x 29
319:11x 29
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.
11x 29 = 319
Therefore, the value for common factors is 319.
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 = 183341369046/(1x319)
LCM = 183341369046/319
LCM = 574737834
Thus, we can understand that the LCM of 643,957,319,934 is 574737834.
