The LCM of 709,357,858,286 is 72390318.
Find LCM of 709,357,858,286 with Prime Factorization
| 2 | 709, 357, 858, 286 |
| 3 | 709, 357, 429, 143 |
| 11 | 709, 119, 143, 143 |
| 13 | 709, 119, 13, 13 |
| 709, 119, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 709 x 119 x 1 x 1 = 72390318
Therefore, the lowest common multiple of 709,357,858,286 is 72390318.
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.
709 x 357 x 858 x 286 = 62110892844
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.
709 : 1, 709
357 : 1, 3, 7, 17, 21, 51, 119, 357
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
286 : 1, 2, 11, 13, 22, 26, 143, 286
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,357,858,286, is 1.
Now, the common factors can be found like this.
709:709
357:3x 7x 17
858:2x 3x 11x 13
286:2x 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 3x 11x 13 = 858
Therefore, the value for common factors is 858.
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 = 62110892844/(1x858)
LCM = 62110892844/858
LCM = 72390318
Thus, we can understand that the LCM of 709,357,858,286 is 72390318.
