Given numbers are 640,898,754,377,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,898,754,377,874 is 47342272640.
Find LCM of 640,898,754,377,874 with Prime Factorization
| 2 | 640, 898, 754, 377, 874 |
| 13 | 320, 449, 377, 377, 437 |
| 29 | 320, 449, 29, 29, 437 |
| 320, 449, 1, 1, 437 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 29 x 320 x 449 x 1 x 1 x 437 = 47342272640
Therefore, the lowest common multiple of 640,898,754,377,874 is 47342272640.
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.
640 x 898 x 754 x 377 x 874 = 142784294282240
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
898 : 1, 2, 449, 898
754 : 1, 2, 13, 26, 29, 58, 377, 754
377 : 1, 13, 29, 377
874 : 1, 2, 19, 23, 38, 46, 437, 874
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,898,754,377,874, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
898:2x 449
754:2x 13x 29
377:13x 29
874:2x 19x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 13x 29 = 3016
Therefore, the value for common factors is 3016.
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 = 142784294282240/(1x3016)
LCM = 142784294282240/3016
LCM = 47342272640
Thus, we can understand that the LCM of 640,898,754,377,874 is 47342272640.
