Given numbers are 665,715,559,513
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,715,559,513 is 110405295.
Find LCM of 665,715,559,513 with Prime Factorization
| 5 | 665, 715, 559, 513 |
| 13 | 133, 143, 559, 513 |
| 19 | 133, 11, 43, 513 |
| 7, 11, 43, 27 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 19 x 7 x 11 x 43 x 27 = 110405295
Therefore, the lowest common multiple of 665,715,559,513 is 110405295.
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.
665 x 715 x 559 x 513 = 136350539325
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
715 : 1, 5, 11, 13, 55, 65, 143, 715
559 : 1, 13, 43, 559
513 : 1, 3, 9, 19, 27, 57, 171, 513
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,715,559,513, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
715:5x 11x 13
559:13x 43
513:3x 3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13x 19 = 1235
Therefore, the value for common factors is 1235.
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 = 136350539325/(1x1235)
LCM = 136350539325/1235
LCM = 110405295
Thus, we can understand that the LCM of 665,715,559,513 is 110405295.
