Given numbers are 749,897,660,855,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,897,660,855,803 is 615027673260.
Find LCM of 749,897,660,855,803 with Prime Factorization
| 3 | 749, 897, 660, 855, 803 |
| 5 | 749, 299, 220, 285, 803 |
| 11 | 749, 299, 44, 57, 803 |
| 749, 299, 4, 57, 73 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 749 x 299 x 4 x 57 x 73 = 615027673260
Therefore, the lowest common multiple of 749,897,660,855,803 is 615027673260.
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.
749 x 897 x 660 x 855 x 803 = 304438698263700
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.
749 : 1, 7, 107, 749
897 : 1, 3, 13, 23, 39, 69, 299, 897
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,897,660,855,803, is 1.
Now, the common factors can be found like this.
749:7x 107
897:3x 13x 23
660:2x 2x 3x 5x 11
855:3x 3x 5x 19
803:11x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 11 = 495
Therefore, the value for common factors is 495.
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 = 304438698263700/(1x495)
LCM = 304438698263700/495
LCM = 615027673260
Thus, we can understand that the LCM of 749,897,660,855,803 is 615027673260.
