| 13 | 33, 13, 689, 227, 4 |
| 33, 1, 53, 227, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 13 x 33 x 1 x 53 x 227 x 4 = 1981938816
Therefore, the lowest common multiple of 396,416,689,681,384 is 1981938816.
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.
396 x 416 x 689 x 681 x 384 = 29681515708416
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
689 : 1, 13, 53, 689
681 : 1, 3, 227, 681
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,416,689,681,384, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
416:2x 2x 2x 2x 2x 13
689:13x 53
681:3x 227
384:2x 2x 2x 2x 2x 2x 2x 3
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 2x 2x 2x 2x 3x 3x 13 = 14976
Therefore, the value for common factors is 14976.
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 = 29681515708416/(1x14976)
LCM = 29681515708416/14976
LCM = 1981938816
Thus, we can understand that the LCM of 396,416,689,681,384 is 1981938816.
