Given numbers are 130,686,465,768,515
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 130,686,465,768,515 is 54672334080.
Find LCM of 130,686,465,768,515 with Prime Factorization
| 2 | 130, 686, 465, 768, 515 |
| 3 | 65, 343, 465, 384, 515 |
| 5 | 65, 343, 155, 128, 515 |
| 13, 343, 31, 128, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 343 x 31 x 128 x 103 = 54672334080
Therefore, the lowest common multiple of 130,686,465,768,515 is 54672334080.
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.
130 x 686 x 465 x 768 x 515 = 16401700224000
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.
130 : 1, 2, 5, 10, 13, 26, 65, 130
686 : 1, 2, 7, 14, 49, 98, 343, 686
465 : 1, 3, 5, 15, 31, 93, 155, 465
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,686,465,768,515, is 1.
Now, the common factors can be found like this.
130:2x 5x 13
686:2x 7x 7x 7
465:3x 5x 31
768:2x 2x 2x 2x 2x 2x 2x 2x 3
515:5x 103
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 16401700224000/(1x300)
LCM = 16401700224000/300
LCM = 54672334080
Thus, we can understand that the LCM of 130,686,465,768,515 is 54672334080.
