Given numbers are 105,916,918,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,916,918,168 is 29431080.
Find LCM of 105,916,918,168 with Prime Factorization
| 2 | 105, 916, 918, 168 |
| 2 | 105, 458, 459, 84 |
| 3 | 105, 229, 459, 42 |
| 7 | 35, 229, 153, 14 |
| 5, 229, 153, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 5 x 229 x 153 x 2 = 29431080
Therefore, the lowest common multiple of 105,916,918,168 is 29431080.
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.
105 x 916 x 918 x 168 = 14833264320
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
916 : 1, 2, 4, 229, 458, 916
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,916,918,168, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
916:2x 2x 229
918:2x 3x 3x 3x 17
168:2x 2x 2x 3x 7
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 2x 3x 3x 7 = 504
Therefore, the value for common factors is 504.
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 = 14833264320/(1x504)
LCM = 14833264320/504
LCM = 29431080
Thus, we can understand that the LCM of 105,916,918,168 is 29431080.
