Given numbers are 587,891,715,531,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 587,891,715,531,642 is 429234821730.
Find LCM of 587,891,715,531,642 with Prime Factorization
| 3 | 587, 891, 715, 531, 642 |
| 3 | 587, 297, 715, 177, 214 |
| 11 | 587, 99, 715, 59, 214 |
| 587, 9, 65, 59, 214 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 587 x 9 x 65 x 59 x 214 = 429234821730
Therefore, the lowest common multiple of 587,891,715,531,642 is 429234821730.
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.
587 x 891 x 715 x 531 x 642 = 127482742053810
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.
587 : 1, 587
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
715 : 1, 5, 11, 13, 55, 65, 143, 715
531 : 1, 3, 9, 59, 177, 531
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 587,891,715,531,642, is 1.
Now, the common factors can be found like this.
587:587
891:3x 3x 3x 3x 11
715:5x 11x 13
531:3x 3x 59
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.
3x 3x 3x 11 = 297
Therefore, the value for common factors is 297.
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 = 127482742053810/(1x297)
LCM = 127482742053810/297
LCM = 429234821730
Thus, we can understand that the LCM of 587,891,715,531,642 is 429234821730.
