Given numbers are 729,861,615,267
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,861,615,267 is 93104235.
Find LCM of 729,861,615,267 with Prime Factorization
| 3 | 729, 861, 615, 267 |
| 41 | 243, 287, 205, 89 |
| 243, 7, 5, 89 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 243 x 7 x 5 x 89 = 93104235
Therefore, the lowest common multiple of 729,861,615,267 is 93104235.
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.
729 x 861 x 615 x 267 = 103066388145
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.
729 : 1, 3, 9, 27, 81, 243, 729
861 : 1, 3, 7, 21, 41, 123, 287, 861
615 : 1, 3, 5, 15, 41, 123, 205, 615
267 : 1, 3, 89, 267
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,861,615,267, is 3.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
861:3x 7x 41
615:3x 5x 41
267:3x 89
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 41 = 369
Therefore, the value for common factors is 369.
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 = 103066388145/(3x369)
LCM = 103066388145/1107
LCM = 93104235
Thus, we can understand that the LCM of 729,861,615,267 is 93104235.
