Given numbers are 396,460,121,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,460,121,771 is 128741580.
Find LCM of 396,460,121,771 with Prime Factorization
| 2 | 396, 460, 121, 771 |
| 2 | 198, 230, 121, 771 |
| 3 | 99, 115, 121, 771 |
| 11 | 33, 115, 121, 257 |
| 3, 115, 11, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 3 x 115 x 11 x 257 = 128741580
Therefore, the lowest common multiple of 396,460,121,771 is 128741580.
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.
396 x 460 x 121 x 771 = 16993888560
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
121 : 1, 11, 121
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,460,121,771, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
460:2x 2x 5x 23
121:11x 11
771:3x 257
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 16993888560/(1x132)
LCM = 16993888560/132
LCM = 128741580
Thus, we can understand that the LCM of 396,460,121,771 is 128741580.
