Given numbers are 822,585,403,555
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,585,403,555 is 183852630.
Find LCM of 822,585,403,555 with Prime Factorization
| 3 | 822, 585, 403, 555 |
| 5 | 274, 195, 403, 185 |
| 13 | 274, 39, 403, 37 |
| 274, 3, 31, 37 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 274 x 3 x 31 x 37 = 183852630
Therefore, the lowest common multiple of 822,585,403,555 is 183852630.
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.
822 x 585 x 403 x 555 = 107553788550
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
403 : 1, 13, 31, 403
555 : 1, 3, 5, 15, 37, 111, 185, 555
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,585,403,555, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
585:3x 3x 5x 13
403:13x 31
555:3x 5x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 13 = 585
Therefore, the value for common factors is 585.
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 = 107553788550/(1x585)
LCM = 107553788550/585
LCM = 183852630
Thus, we can understand that the LCM of 822,585,403,555 is 183852630.
