Given numbers are 768,707,813,266,669
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,707,813,266,669 is 623459703552.
Find LCM of 768,707,813,266,669 with Prime Factorization
| 2 | 768, 707, 813, 266, 669 |
| 3 | 384, 707, 813, 133, 669 |
| 7 | 128, 707, 271, 133, 223 |
| 128, 101, 271, 19, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 128 x 101 x 271 x 19 x 223 = 623459703552
Therefore, the lowest common multiple of 768,707,813,266,669 is 623459703552.
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 707 x 813 x 266 x 669 = 78555922647552
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
707 : 1, 7, 101, 707
813 : 1, 3, 271, 813
266 : 1, 2, 7, 14, 19, 38, 133, 266
669 : 1, 3, 223, 669
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,707,813,266,669, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
707:7x 101
813:3x 271
266:2x 7x 19
669:3x 223
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 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 78555922647552/(1x126)
LCM = 78555922647552/126
LCM = 623459703552
Thus, we can understand that the LCM of 768,707,813,266,669 is 623459703552.
