Given numbers are 312,138,160,414,922
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 312,138,160,414,922 is 198488160.
Find LCM of 312,138,160,414,922 with Prime Factorization
| 2 | 312, 138, 160, 414, 922 |
| 2 | 156, 69, 80, 207, 461 |
| 2 | 78, 69, 40, 207, 461 |
| 3 | 39, 69, 20, 207, 461 |
| 23 | 13, 23, 20, 69, 461 |
| 13, 1, 20, 3, 461 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 23 x 13 x 1 x 20 x 3 x 461 = 198488160
Therefore, the lowest common multiple of 312,138,160,414,922 is 198488160.
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.
312 x 138 x 160 x 414 x 922 = 2629571143680
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
138 : 1, 2, 3, 6, 23, 46, 69, 138
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
922 : 1, 2, 461, 922
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,138,160,414,922, is 2.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
138:2x 3x 23
160:2x 2x 2x 2x 2x 5
414:2x 3x 3x 23
922:2x 461
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 2x 2x 3x 3x 23 = 6624
Therefore, the value for common factors is 6624.
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 = 2629571143680/(2x6624)
LCM = 2629571143680/13248
LCM = 198488160
Thus, we can understand that the LCM of 312,138,160,414,922 is 198488160.
