| 3 | 3, 199, 671, 51, 17 |
| 17 | 1, 199, 671, 17, 17 |
| 1, 199, 671, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 3 x 17 x 1 x 199 x 671 x 1 x 1 = 980636976
Therefore, the lowest common multiple of 432,398,671,459,816 is 980636976.
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.
432 x 398 x 671 x 459 x 816 = 43210787710464
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.
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
398 : 1, 2, 199, 398
671 : 1, 11, 61, 671
459 : 1, 3, 9, 17, 27, 51, 153, 459
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,398,671,459,816, is 1.
Now, the common factors can be found like this.
432:2x 2x 2x 2x 3x 3x 3
398:2x 199
671:11x 61
459:3x 3x 3x 17
816:2x 2x 2x 2x 3x 17
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 3x 3x 3x 3x 17 = 44064
Therefore, the value for common factors is 44064.
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 = 43210787710464/(1x44064)
LCM = 43210787710464/44064
LCM = 980636976
Thus, we can understand that the LCM of 432,398,671,459,816 is 980636976.
