Given numbers are 816,316,721,287,676
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,316,721,287,676 is 322049831376.
Find LCM of 816,316,721,287,676 with Prime Factorization
| 2 | 816, 316, 721, 287, 676 |
| 2 | 408, 158, 721, 287, 338 |
| 7 | 204, 79, 721, 287, 169 |
| 204, 79, 103, 41, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 204 x 79 x 103 x 41 x 169 = 322049831376
Therefore, the lowest common multiple of 816,316,721,287,676 is 322049831376.
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.
816 x 316 x 721 x 287 x 676 = 36069581114112
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
316 : 1, 2, 4, 79, 158, 316
721 : 1, 7, 103, 721
287 : 1, 7, 41, 287
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,316,721,287,676, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
316:2x 2x 79
721:7x 103
287:7x 41
676:2x 2x 13x 13
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 7 = 112
Therefore, the value for common factors is 112.
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 = 36069581114112/(1x112)
LCM = 36069581114112/112
LCM = 322049831376
Thus, we can understand that the LCM of 816,316,721,287,676 is 322049831376.
