Given numbers are 768,246,991,909,725
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,246,991,909,725 is 6854872262400.
Find LCM of 768,246,991,909,725 with Prime Factorization
| 2 | 768, 246, 991, 909, 725 |
| 3 | 384, 123, 991, 909, 725 |
| 128, 41, 991, 303, 725 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 128 x 41 x 991 x 303 x 725 = 6854872262400
Therefore, the lowest common multiple of 768,246,991,909,725 is 6854872262400.
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.
768 x 246 x 991 x 909 x 725 = 123387700723200
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
246 : 1, 2, 3, 6, 41, 82, 123, 246
991 : 1, 991
909 : 1, 3, 9, 101, 303, 909
725 : 1, 5, 25, 29, 145, 725
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,246,991,909,725, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
246:2x 3x 41
991:991
909:3x 3x 101
725:5x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 123387700723200/(1x18)
LCM = 123387700723200/18
LCM = 6854872262400
Thus, we can understand that the LCM of 768,246,991,909,725 is 6854872262400.
