Given numbers are 154,616,330,928
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,616,330,928 is 1071840.
Find LCM of 154,616,330,928 with Prime Factorization
| 2 | 154, 616, 330, 928 |
| 2 | 77, 308, 165, 464 |
| 2 | 77, 154, 165, 232 |
| 7 | 77, 77, 165, 116 |
| 11 | 11, 11, 165, 116 |
| 1, 1, 15, 116 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 11 x 1 x 1 x 15 x 116 = 1071840
Therefore, the lowest common multiple of 154,616,330,928 is 1071840.
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.
154 x 616 x 330 x 928 = 29051151360
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,616,330,928, is 2.
Now, the common factors can be found like this.
154:2x 7x 11
616:2x 2x 2x 7x 11
330:2x 3x 5x 11
928:2x 2x 2x 2x 2x 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 2x 2x 7x 11x 11 = 13552
Therefore, the value for common factors is 13552.
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 = 29051151360/(2x13552)
LCM = 29051151360/27104
LCM = 1071840
Thus, we can understand that the LCM of 154,616,330,928 is 1071840.
