Given numbers are 615,691,915,901,159
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,691,915,901,159 is 23356501365.
Find LCM of 615,691,915,901,159 with Prime Factorization
| 3 | 615, 691, 915, 901, 159 |
| 5 | 205, 691, 305, 901, 53 |
| 53 | 41, 691, 61, 901, 53 |
| 41, 691, 61, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 53 x 41 x 691 x 61 x 17 x 1 = 23356501365
Therefore, the lowest common multiple of 615,691,915,901,159 is 23356501365.
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.
615 x 691 x 915 x 901 x 159 = 55705255755525
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
691 : 1, 691
915 : 1, 3, 5, 15, 61, 183, 305, 915
901 : 1, 17, 53, 901
159 : 1, 3, 53, 159
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,691,915,901,159, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
691:691
915:3x 5x 61
901:17x 53
159:3x 53
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 5x 53 = 2385
Therefore, the value for common factors is 2385.
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 = 55705255755525/(1x2385)
LCM = 55705255755525/2385
LCM = 23356501365
Thus, we can understand that the LCM of 615,691,915,901,159 is 23356501365.
