Given numbers are 122,488,418,253,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 122,488,418,253,667 is 68028664.
Find LCM of 122,488,418,253,667 with Prime Factorization
| 2 | 122, 488, 418, 253, 667 |
| 11 | 61, 244, 209, 253, 667 |
| 23 | 61, 244, 19, 23, 667 |
| 61 | 61, 244, 19, 1, 29 |
| 1, 4, 19, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 23 x 61 x 1 x 4 x 19 x 1 x 29 = 68028664
Therefore, the lowest common multiple of 122,488,418,253,667 is 68028664.
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 488 x 418 x 253 x 667 = 4199545486048
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
488 : 1, 2, 4, 8, 61, 122, 244, 488
418 : 1, 2, 11, 19, 22, 38, 209, 418
253 : 1, 11, 23, 253
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,488,418,253,667, is 1.
Now, the common factors can be found like this.
122:2x 61
488:2x 2x 2x 61
418:2x 11x 19
253:11x 23
667:23x 29
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 11x 23x 61 = 61732
Therefore, the value for common factors is 61732.
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 = 4199545486048/(1x61732)
LCM = 4199545486048/61732
LCM = 68028664
Thus, we can understand that the LCM of 122,488,418,253,667 is 68028664.
