Given numbers are 768,526,836,668
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,526,836,668 is 7049847552.
Find LCM of 768,526,836,668 with Prime Factorization
| 2 | 768, 526, 836, 668 |
| 2 | 384, 263, 418, 334 |
| 192, 263, 209, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 192 x 263 x 209 x 167 = 7049847552
Therefore, the lowest common multiple of 768,526,836,668 is 7049847552.
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 526 x 836 x 668 = 225595121664
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
526 : 1, 2, 263, 526
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
668 : 1, 2, 4, 167, 334, 668
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,526,836,668, is 2.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
526:2x 263
836:2x 2x 11x 19
668:2x 2x 167
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 225595121664/(2x16)
LCM = 225595121664/32
LCM = 7049847552
Thus, we can understand that the LCM of 768,526,836,668 is 7049847552.
