Find LCM of 281,864,721,308,539 with Prime Factorization
| 2 | 281, 864, 721, 308, 539 |
| 2 | 281, 432, 721, 154, 539 |
| 7 | 281, 216, 721, 77, 539 |
| 11 | 281, 216, 103, 11, 77 |
| 281, 216, 103, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 281 x 216 x 103 x 1 x 7 = 13478639328
Therefore, the lowest common multiple of 281,864,721,308,539 is 13478639328.
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.
281 x 864 x 721 x 308 x 539 = 29059946391168
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.
281 : 1, 281
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
721 : 1, 7, 103, 721
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
539 : 1, 7, 11, 49, 77, 539
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,864,721,308,539, is 1.
Now, the common factors can be found like this.
281:281
864:2x 2x 2x 2x 2x 3x 3x 3
721:7x 103
308:2x 2x 7x 11
539:7x 7x 11
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 7x 7x 11 = 2156
Therefore, the value for common factors is 2156.
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 = 29059946391168/(1x2156)
LCM = 29059946391168/2156
LCM = 13478639328
Thus, we can understand that the LCM of 281,864,721,308,539 is 13478639328.
