The LCM of 762,391,855,760 is 339653880.
Find LCM of 762,391,855,760 with Prime Factorization
| 2 | 762, 391, 855, 760 |
| 3 | 381, 391, 855, 380 |
| 5 | 127, 391, 285, 380 |
| 19 | 127, 391, 57, 76 |
| 127, 391, 3, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 127 x 391 x 3 x 4 = 339653880
Therefore, the lowest common multiple of 762,391,855,760 is 339653880.
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.
762 x 391 x 855 x 760 = 193602711600
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
391 : 1, 17, 23, 391
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,391,855,760, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
391:17x 23
855:3x 3x 5x 19
760:2x 2x 2x 5x 19
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 5x 19 = 570
Therefore, the value for common factors is 570.
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 = 193602711600/(1x570)
LCM = 193602711600/570
LCM = 339653880
Thus, we can understand that the LCM of 762,391,855,760 is 339653880.
