Given numbers are 159,328,987,869,518
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 159,328,987,869,518 is 551681431224.
Find LCM of 159,328,987,869,518 with Prime Factorization
| 2 | 159, 328, 987, 869, 518 |
| 3 | 159, 164, 987, 869, 259 |
| 7 | 53, 164, 329, 869, 259 |
| 53, 164, 47, 869, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 53 x 164 x 47 x 869 x 37 = 551681431224
Therefore, the lowest common multiple of 159,328,987,869,518 is 551681431224.
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.
159 x 328 x 987 x 869 x 518 = 23170620111408
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.
159 : 1, 3, 53, 159
328 : 1, 2, 4, 8, 41, 82, 164, 328
987 : 1, 3, 7, 21, 47, 141, 329, 987
869 : 1, 11, 79, 869
518 : 1, 2, 7, 14, 37, 74, 259, 518
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 159,328,987,869,518, is 1.
Now, the common factors can be found like this.
159:3x 53
328:2x 2x 2x 41
987:3x 7x 47
869:11x 79
518:2x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 23170620111408/(1x42)
LCM = 23170620111408/42
LCM = 551681431224
Thus, we can understand that the LCM of 159,328,987,869,518 is 551681431224.
