Given numbers are 901,621,162,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 901,621,162,768 is 429712128.
Find LCM of 901,621,162,768 with Prime Factorization
| 2 | 901, 621, 162, 768 |
| 3 | 901, 621, 81, 384 |
| 3 | 901, 207, 27, 128 |
| 3 | 901, 69, 9, 128 |
| 901, 23, 3, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 901 x 23 x 3 x 128 = 429712128
Therefore, the lowest common multiple of 901,621,162,768 is 429712128.
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.
901 x 621 x 162 x 768 = 69613364736
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.
901 : 1, 17, 53, 901
621 : 1, 3, 9, 23, 27, 69, 207, 621
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,621,162,768, is 1.
Now, the common factors can be found like this.
901:17x 53
621:3x 3x 3x 23
162:2x 3x 3x 3x 3
768:2x 2x 2x 2x 2x 2x 2x 2x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 69613364736/(1x162)
LCM = 69613364736/162
LCM = 429712128
Thus, we can understand that the LCM of 901,621,162,768 is 429712128.
