Given numbers are 920,820,820,395,866
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,820,820,395,866 is 1290288040.
Find LCM of 920,820,820,395,866 with Prime Factorization
| 2 | 920, 820, 820, 395, 866 |
| 2 | 460, 410, 410, 395, 433 |
| 5 | 230, 205, 205, 395, 433 |
| 41 | 46, 41, 41, 79, 433 |
| 46, 1, 1, 79, 433 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 41 x 46 x 1 x 1 x 79 x 433 = 1290288040
Therefore, the lowest common multiple of 920,820,820,395,866 is 1290288040.
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 820 x 820 x 395 x 866 = 211607238560000
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
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
395 : 1, 5, 79, 395
866 : 1, 2, 433, 866
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,820,820,395,866, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
820:2x 2x 5x 41
820:2x 2x 5x 41
395:5x 79
866:2x 433
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 5x 5x 5x 41 = 164000
Therefore, the value for common factors is 164000.
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 = 211607238560000/(1x164000)
LCM = 211607238560000/164000
LCM = 1290288040
Thus, we can understand that the LCM of 920,820,820,395,866 is 1290288040.
