The LCM of 430,361,782,819,105 is 49709147670.
Find LCM of 430,361,782,819,105 with Prime Factorization
| 2 | 430, 361, 782, 819, 105 |
| 3 | 215, 361, 391, 819, 105 |
| 5 | 215, 361, 391, 273, 35 |
| 7 | 43, 361, 391, 273, 7 |
| 43, 361, 391, 39, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 43 x 361 x 391 x 39 x 1 = 49709147670
Therefore, the lowest common multiple of 430,361,782,819,105 is 49709147670.
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.
430 x 361 x 782 x 819 x 105 = 10438921010700
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.
430 : 1, 2, 5, 10, 43, 86, 215, 430
361 : 1, 19, 361
782 : 1, 2, 17, 23, 34, 46, 391, 782
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,361,782,819,105, is 1.
Now, the common factors can be found like this.
430:2x 5x 43
361:19x 19
782:2x 17x 23
819:3x 3x 7x 13
105:3x 5x 7
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 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 10438921010700/(1x210)
LCM = 10438921010700/210
LCM = 49709147670
Thus, we can understand that the LCM of 430,361,782,819,105 is 49709147670.
