Given numbers are 287,136,886,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,136,886,897 is 15510184872.
Find LCM of 287,136,886,897 with Prime Factorization
| 2 | 287, 136, 886, 897 |
| 287, 68, 443, 897 |
Multiply the prime numbers at the bottom and the left side.
2 x 287 x 68 x 443 x 897 = 15510184872
Therefore, the lowest common multiple of 287,136,886,897 is 15510184872.
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.
287 x 136 x 886 x 897 = 31020369744
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.
287 : 1, 7, 41, 287
136 : 1, 2, 4, 8, 17, 34, 68, 136
886 : 1, 2, 443, 886
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,136,886,897, is 1.
Now, the common factors can be found like this.
287:7x 41
136:2x 2x 2x 17
886:2x 443
897:3x 13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 31020369744/(1x2)
LCM = 31020369744/2
LCM = 15510184872
Thus, we can understand that the LCM of 287,136,886,897 is 15510184872.
