Given numbers are 920,768,828,653
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,768,828,653 is 173018880.
Find LCM of 920,768,828,653 with Prime Factorization
| 2 | 920, 768, 828, 653 |
| 2 | 460, 384, 414, 653 |
| 2 | 230, 192, 207, 653 |
| 3 | 115, 96, 207, 653 |
| 23 | 115, 32, 69, 653 |
| 5, 32, 3, 653 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 23 x 5 x 32 x 3 x 653 = 173018880
Therefore, the lowest common multiple of 920,768,828,653 is 173018880.
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.
920 x 768 x 828 x 653 = 382025687040
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
653 : 1, 653
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,768,828,653, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
768:2x 2x 2x 2x 2x 2x 2x 2x 3
828:2x 2x 3x 3x 23
653:653
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 2x 3x 23 = 2208
Therefore, the value for common factors is 2208.
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 = 382025687040/(1x2208)
LCM = 382025687040/2208
LCM = 173018880
Thus, we can understand that the LCM of 920,768,828,653 is 173018880.
