Given numbers are 844,455,770,820,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,455,770,820,100 is 865965100.
Find LCM of 844,455,770,820,100 with Prime Factorization
| 2 | 844, 455, 770, 820, 100 |
| 2 | 422, 455, 385, 410, 50 |
| 5 | 211, 455, 385, 205, 25 |
| 7 | 211, 91, 77, 41, 5 |
| 211, 13, 11, 41, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 211 x 13 x 11 x 41 x 5 = 865965100
Therefore, the lowest common multiple of 844,455,770,820,100 is 865965100.
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.
844 x 455 x 770 x 820 x 100 = 24247022800000
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.
844 : 1, 2, 4, 211, 422, 844
455 : 1, 5, 7, 13, 35, 65, 91, 455
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,455,770,820,100, is 1.
Now, the common factors can be found like this.
844:2x 2x 211
455:5x 7x 13
770:2x 5x 7x 11
820:2x 2x 5x 41
100:2x 2x 5x 5
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 7 = 28000
Therefore, the value for common factors is 28000.
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 = 24247022800000/(1x28000)
LCM = 24247022800000/28000
LCM = 865965100
Thus, we can understand that the LCM of 844,455,770,820,100 is 865965100.
