Given numbers are 768,695,865,291
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,695,865,291 is 8957026560.
Find LCM of 768,695,865,291 with Prime Factorization
| 3 | 768, 695, 865, 291 |
| 5 | 256, 695, 865, 97 |
| 256, 139, 173, 97 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 256 x 139 x 173 x 97 = 8957026560
Therefore, the lowest common multiple of 768,695,865,291 is 8957026560.
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 695 x 865 x 291 = 134355398400
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
695 : 1, 5, 139, 695
865 : 1, 5, 173, 865
291 : 1, 3, 97, 291
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,695,865,291, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
695:5x 139
865:5x 173
291:3x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 134355398400/(1x15)
LCM = 134355398400/15
LCM = 8957026560
Thus, we can understand that the LCM of 768,695,865,291 is 8957026560.
