The LCM of 580,399,986,858 is 562582020.
Find LCM of 580,399,986,858 with Prime Factorization
| 2 | 580, 399, 986, 858 |
| 3 | 290, 399, 493, 429 |
| 29 | 290, 133, 493, 143 |
| 10, 133, 17, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 10 x 133 x 17 x 143 = 562582020
Therefore, the lowest common multiple of 580,399,986,858 is 562582020.
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.
580 x 399 x 986 x 858 = 195778542960
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.
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
399 : 1, 3, 7, 19, 21, 57, 133, 399
986 : 1, 2, 17, 29, 34, 58, 493, 986
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 580,399,986,858, is 1.
Now, the common factors can be found like this.
580:2x 2x 5x 29
399:3x 7x 19
986:2x 17x 29
858:2x 3x 11x 13
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 3x 29 = 348
Therefore, the value for common factors is 348.
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 = 195778542960/(1x348)
LCM = 195778542960/348
LCM = 562582020
Thus, we can understand that the LCM of 580,399,986,858 is 562582020.
