The LCM of 802,247,387,585 is 383311890.
Find LCM of 802,247,387,585 with Prime Factorization
| 3 | 802, 247, 387, 585 |
| 3 | 802, 247, 129, 195 |
| 13 | 802, 247, 43, 65 |
| 802, 19, 43, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 802 x 19 x 43 x 5 = 383311890
Therefore, the lowest common multiple of 802,247,387,585 is 383311890.
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.
802 x 247 x 387 x 585 = 44847491130
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.
802 : 1, 2, 401, 802
247 : 1, 13, 19, 247
387 : 1, 3, 9, 43, 129, 387
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,247,387,585, is 1.
Now, the common factors can be found like this.
802:2x 401
247:13x 19
387:3x 3x 43
585:3x 3x 5x 13
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 13 = 117
Therefore, the value for common factors is 117.
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 = 44847491130/(1x117)
LCM = 44847491130/117
LCM = 383311890
Thus, we can understand that the LCM of 802,247,387,585 is 383311890.
