The LCM of 261,754,629,391,740 is 981730620.
Find LCM of 261,754,629,391,740 with Prime Factorization
| 2 | 261, 754, 629, 391, 740 |
| 17 | 261, 377, 629, 391, 370 |
| 29 | 261, 377, 37, 23, 370 |
| 37 | 9, 13, 37, 23, 370 |
| 9, 13, 1, 23, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 29 x 37 x 9 x 13 x 1 x 23 x 10 = 981730620
Therefore, the lowest common multiple of 261,754,629,391,740 is 981730620.
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.
261 x 754 x 629 x 391 x 740 = 35815496478840
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.
261 : 1, 3, 9, 29, 87, 261
754 : 1, 2, 13, 26, 29, 58, 377, 754
629 : 1, 17, 37, 629
391 : 1, 17, 23, 391
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,754,629,391,740, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
754:2x 13x 29
629:17x 37
391:17x 23
740:2x 2x 5x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 29x 37 = 36482
Therefore, the value for common factors is 36482.
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 = 35815496478840/(1x36482)
LCM = 35815496478840/36482
LCM = 981730620
Thus, we can understand that the LCM of 261,754,629,391,740 is 981730620.
