Given numbers are 591,985,858,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 591,985,858,642 is 90428910.
Find LCM of 591,985,858,642 with Prime Factorization
| 2 | 591, 985, 858, 642 |
| 3 | 591, 985, 429, 321 |
| 197 | 197, 985, 143, 107 |
| 1, 5, 143, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 197 x 1 x 5 x 143 x 107 = 90428910
Therefore, the lowest common multiple of 591,985,858,642 is 90428910.
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.
591 x 985 x 858 x 642 = 320660914860
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.
591 : 1, 3, 197, 591
985 : 1, 5, 197, 985
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 591,985,858,642, is 1.
Now, the common factors can be found like this.
591:3x 197
985:5x 197
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 3x 3x 197 = 3546
Therefore, the value for common factors is 3546.
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 = 320660914860/(1x3546)
LCM = 320660914860/3546
LCM = 90428910
Thus, we can understand that the LCM of 591,985,858,642 is 90428910.
