Given numbers are 162,516,698,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 162,516,698,855 is 461915460.
Find LCM of 162,516,698,855 with Prime Factorization
| 2 | 162, 516, 698, 855 |
| 3 | 81, 258, 349, 855 |
| 3 | 27, 86, 349, 285 |
| 9, 86, 349, 95 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 9 x 86 x 349 x 95 = 461915460
Therefore, the lowest common multiple of 162,516,698,855 is 461915460.
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.
162 x 516 x 698 x 855 = 49886869680
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.
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
698 : 1, 2, 349, 698
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,516,698,855, is 1.
Now, the common factors can be found like this.
162:2x 3x 3x 3x 3
516:2x 2x 3x 43
698:2x 349
855:3x 3x 5x 19
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 49886869680/(1x108)
LCM = 49886869680/108
LCM = 461915460
Thus, we can understand that the LCM of 162,516,698,855 is 461915460.
