Given numbers are 131,834,621,287,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,834,621,287,874 is 123322746834.
Find LCM of 131,834,621,287,874 with Prime Factorization
| 2 | 131, 834, 621, 287, 874 |
| 3 | 131, 417, 621, 287, 437 |
| 23 | 131, 139, 207, 287, 437 |
| 131, 139, 9, 287, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 131 x 139 x 9 x 287 x 19 = 123322746834
Therefore, the lowest common multiple of 131,834,621,287,874 is 123322746834.
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.
131 x 834 x 621 x 287 x 874 = 17018539063092
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.
131 : 1, 131
834 : 1, 2, 3, 6, 139, 278, 417, 834
621 : 1, 3, 9, 23, 27, 69, 207, 621
287 : 1, 7, 41, 287
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 131,834,621,287,874, is 1.
Now, the common factors can be found like this.
131:131
834:2x 3x 139
621:3x 3x 3x 23
287:7x 41
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 3x 23 = 138
Therefore, the value for common factors is 138.
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 = 17018539063092/(1x138)
LCM = 17018539063092/138
LCM = 123322746834
Thus, we can understand that the LCM of 131,834,621,287,874 is 123322746834.
