Given numbers are 779,784,377,338,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,784,377,338,817 is 128708336848.
Find LCM of 779,784,377,338,817 with Prime Factorization
| 2 | 779, 784, 377, 338, 817 |
| 13 | 779, 392, 377, 169, 817 |
| 19 | 779, 392, 29, 13, 817 |
| 41, 392, 29, 13, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 41 x 392 x 29 x 13 x 43 = 128708336848
Therefore, the lowest common multiple of 779,784,377,338,817 is 128708336848.
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.
779 x 784 x 377 x 338 x 817 = 63581918402912
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.
779 : 1, 19, 41, 779
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
377 : 1, 13, 29, 377
338 : 1, 2, 13, 26, 169, 338
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,784,377,338,817, is 1.
Now, the common factors can be found like this.
779:19x 41
784:2x 2x 2x 2x 7x 7
377:13x 29
338:2x 13x 13
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 19 = 494
Therefore, the value for common factors is 494.
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 = 63581918402912/(1x494)
LCM = 63581918402912/494
LCM = 128708336848
Thus, we can understand that the LCM of 779,784,377,338,817 is 128708336848.
