Given numbers are 768,760,668,156
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,760,668,156 is 158396160.
Find LCM of 768,760,668,156 with Prime Factorization
| 2 | 768, 760, 668, 156 |
| 2 | 384, 380, 334, 78 |
| 2 | 192, 190, 167, 39 |
| 3 | 96, 95, 167, 39 |
| 32, 95, 167, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 32 x 95 x 167 x 13 = 158396160
Therefore, the lowest common multiple of 768,760,668,156 is 158396160.
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 760 x 668 x 156 = 60824125440
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
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
668 : 1, 2, 4, 167, 334, 668
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,760,668,156, is 4.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
760:2x 2x 2x 5x 19
668:2x 2x 167
156:2x 2x 3x 13
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 2x 2x 3 = 96
Therefore, the value for common factors is 96.
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 = 60824125440/(4x96)
LCM = 60824125440/384
LCM = 158396160
Thus, we can understand that the LCM of 768,760,668,156 is 158396160.
