Given numbers are 916,155,492,810,122
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 916,155,492,810,122 is 28762450380.
Find LCM of 916,155,492,810,122 with Prime Factorization
| 2 | 916, 155, 492, 810, 122 |
| 2 | 458, 155, 246, 405, 61 |
| 3 | 229, 155, 123, 405, 61 |
| 5 | 229, 155, 41, 135, 61 |
| 229, 31, 41, 27, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 229 x 31 x 41 x 27 x 61 = 28762450380
Therefore, the lowest common multiple of 916,155,492,810,122 is 28762450380.
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.
916 x 155 x 492 x 810 x 122 = 6902988091200
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.
916 : 1, 2, 4, 229, 458, 916
155 : 1, 5, 31, 155
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
122 : 1, 2, 61, 122
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,155,492,810,122, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
155:5x 31
492:2x 2x 3x 41
810:2x 3x 3x 3x 3x 5
122:2x 61
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 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 6902988091200/(1x240)
LCM = 6902988091200/240
LCM = 28762450380
Thus, we can understand that the LCM of 916,155,492,810,122 is 28762450380.
