Given numbers are 121,605,928,906,637
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 121,605,928,906,637 is 162009687840.
Find LCM of 121,605,928,906,637 with Prime Factorization
| 2 | 121, 605, 928, 906, 637 |
| 11 | 121, 605, 464, 453, 637 |
| 11 | 11, 55, 464, 453, 637 |
| 1, 5, 464, 453, 637 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 11 x 1 x 5 x 464 x 453 x 637 = 162009687840
Therefore, the lowest common multiple of 121,605,928,906,637 is 162009687840.
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.
121 x 605 x 928 x 906 x 637 = 39206344457280
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.
121 : 1, 11, 121
605 : 1, 5, 11, 55, 121, 605
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
906 : 1, 2, 3, 6, 151, 302, 453, 906
637 : 1, 7, 13, 49, 91, 637
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,605,928,906,637, is 1.
Now, the common factors can be found like this.
121:11x 11
605:5x 11x 11
928:2x 2x 2x 2x 2x 29
906:2x 3x 151
637:7x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 39206344457280/(1x242)
LCM = 39206344457280/242
LCM = 162009687840
Thus, we can understand that the LCM of 121,605,928,906,637 is 162009687840.
