Given numbers are 741,381,416,731,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,381,416,731,870 is 319195886880.
Find LCM of 741,381,416,731,870 with Prime Factorization
| 2 | 741, 381, 416, 731, 870 |
| 3 | 741, 381, 208, 731, 435 |
| 13 | 247, 127, 208, 731, 145 |
| 19, 127, 16, 731, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 19 x 127 x 16 x 731 x 145 = 319195886880
Therefore, the lowest common multiple of 741,381,416,731,870 is 319195886880.
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.
741 x 381 x 416 x 731 x 870 = 74691837529920
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
381 : 1, 3, 127, 381
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
731 : 1, 17, 43, 731
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,381,416,731,870, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
381:3x 127
416:2x 2x 2x 2x 2x 13
731:17x 43
870:2x 3x 5x 29
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 13 = 234
Therefore, the value for common factors is 234.
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 = 74691837529920/(1x234)
LCM = 74691837529920/234
LCM = 319195886880
Thus, we can understand that the LCM of 741,381,416,731,870 is 319195886880.
