Given numbers are 705,100,585,820,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,100,585,820,816 is 1533121200.
Find LCM of 705,100,585,820,816 with Prime Factorization
| 2 | 705, 100, 585, 820, 816 |
| 2 | 705, 50, 585, 410, 408 |
| 3 | 705, 25, 585, 205, 204 |
| 5 | 235, 25, 195, 205, 68 |
| 47, 5, 39, 41, 68 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 47 x 5 x 39 x 41 x 68 = 1533121200
Therefore, the lowest common multiple of 705,100,585,820,816 is 1533121200.
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.
705 x 100 x 585 x 820 x 816 = 27596181600000
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,100,585,820,816, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
100:2x 2x 5x 5
585:3x 3x 5x 13
820:2x 2x 5x 41
816:2x 2x 2x 2x 3x 17
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 3x 3x 5x 5x 5 = 18000
Therefore, the value for common factors is 18000.
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 = 27596181600000/(1x18000)
LCM = 27596181600000/18000
LCM = 1533121200
Thus, we can understand that the LCM of 705,100,585,820,816 is 1533121200.
