Given numbers are 297,741,454,798,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 297,741,454,798,689 is 12356149806.
Find LCM of 297,741,454,798,689 with Prime Factorization
| 2 | 297, 741, 454, 798, 689 |
| 3 | 297, 741, 227, 399, 689 |
| 13 | 99, 247, 227, 133, 689 |
| 19 | 99, 19, 227, 133, 53 |
| 99, 1, 227, 7, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 19 x 99 x 1 x 227 x 7 x 53 = 12356149806
Therefore, the lowest common multiple of 297,741,454,798,689 is 12356149806.
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.
297 x 741 x 454 x 798 x 689 = 54935442037476
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.
297 : 1, 3, 9, 11, 27, 33, 99, 297
741 : 1, 3, 13, 19, 39, 57, 247, 741
454 : 1, 2, 227, 454
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,741,454,798,689, is 1.
Now, the common factors can be found like this.
297:3x 3x 3x 11
741:3x 13x 19
454:2x 227
798:2x 3x 7x 19
689:13x 53
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 13x 19 = 4446
Therefore, the value for common factors is 4446.
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 = 54935442037476/(1x4446)
LCM = 54935442037476/4446
LCM = 12356149806
Thus, we can understand that the LCM of 297,741,454,798,689 is 12356149806.
