Given numbers are 918,417,603,412,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 918,417,603,412,645 is 378650002860.
Find LCM of 918,417,603,412,645 with Prime Factorization
| 2 | 918, 417, 603, 412, 645 |
| 3 | 459, 417, 603, 206, 645 |
| 3 | 153, 139, 201, 206, 215 |
| 51, 139, 67, 206, 215 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 51 x 139 x 67 x 206 x 215 = 378650002860
Therefore, the lowest common multiple of 918,417,603,412,645 is 378650002860.
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.
918 x 417 x 603 x 412 x 645 = 61341300463320
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
417 : 1, 3, 139, 417
603 : 1, 3, 9, 67, 201, 603
412 : 1, 2, 4, 103, 206, 412
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,417,603,412,645, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
417:3x 139
603:3x 3x 67
412:2x 2x 103
645:3x 5x 43
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 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 61341300463320/(1x162)
LCM = 61341300463320/162
LCM = 378650002860
Thus, we can understand that the LCM of 918,417,603,412,645 is 378650002860.
