Find LCM of 529,462,858,642 with Prime Factorization
| 2 | 529, 462, 858, 642 |
| 3 | 529, 231, 429, 321 |
| 11 | 529, 77, 143, 107 |
| 529, 7, 13, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 529 x 7 x 13 x 107 = 339957618
Therefore, the lowest common multiple of 529,462,858,642 is 339957618.
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.
529 x 462 x 858 x 642 = 134623216728
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.
529 : 1, 23, 529
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 529,462,858,642, is 1.
Now, the common factors can be found like this.
529:23x 23
462:2x 3x 7x 11
858:2x 3x 11x 13
642:2x 3x 107
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 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 134623216728/(1x396)
LCM = 134623216728/396
LCM = 339957618
Thus, we can understand that the LCM of 529,462,858,642 is 339957618.
