Find LCM of 664,779,399,328 with Prime Factorization
| 2 | 664, 779, 399, 328 |
| 2 | 332, 779, 399, 164 |
| 2 | 166, 779, 399, 82 |
| 19 | 83, 779, 399, 41 |
| 41 | 83, 41, 21, 41 |
| 83, 1, 21, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 41 x 83 x 1 x 21 x 1 = 10862376
Therefore, the lowest common multiple of 664,779,399,328 is 10862376.
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.
664 x 779 x 399 x 328 = 67694327232
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.
664 : 1, 2, 4, 8, 83, 166, 332, 664
779 : 1, 19, 41, 779
399 : 1, 3, 7, 19, 21, 57, 133, 399
328 : 1, 2, 4, 8, 41, 82, 164, 328
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,779,399,328, is 1.
Now, the common factors can be found like this.
664:2x 2x 2x 83
779:19x 41
399:3x 7x 19
328:2x 2x 2x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 19x 41 = 6232
Therefore, the value for common factors is 6232.
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 = 67694327232/(1x6232)
LCM = 67694327232/6232
LCM = 10862376
Thus, we can understand that the LCM of 664,779,399,328 is 10862376.
