Given numbers are 122,979,640,786,330
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 122,979,640,786,330 is 15020522880.
Find LCM of 122,979,640,786,330 with Prime Factorization
| 2 | 122, 979, 640, 786, 330 |
| 3 | 61, 979, 320, 393, 165 |
| 5 | 61, 979, 320, 131, 55 |
| 11 | 61, 979, 64, 131, 11 |
| 61, 89, 64, 131, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 61 x 89 x 64 x 131 x 1 = 15020522880
Therefore, the lowest common multiple of 122,979,640,786,330 is 15020522880.
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.
122 x 979 x 640 x 786 x 330 = 19827090201600
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.
122 : 1, 2, 61, 122
979 : 1, 11, 89, 979
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
786 : 1, 2, 3, 6, 131, 262, 393, 786
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,979,640,786,330, is 1.
Now, the common factors can be found like this.
122:2x 61
979:11x 89
640:2x 2x 2x 2x 2x 2x 2x 5
786:2x 3x 131
330:2x 3x 5x 11
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 5x 11 = 1320
Therefore, the value for common factors is 1320.
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 = 19827090201600/(1x1320)
LCM = 19827090201600/1320
LCM = 15020522880
Thus, we can understand that the LCM of 122,979,640,786,330 is 15020522880.
