Given numbers are 131,978,249,682,231
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,978,249,682,231 is 25382866278.
Find LCM of 131,978,249,682,231 with Prime Factorization
| 2 | 131, 978, 249, 682, 231 |
| 3 | 131, 489, 249, 341, 231 |
| 11 | 131, 163, 83, 341, 77 |
| 131, 163, 83, 31, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 131 x 163 x 83 x 31 x 7 = 25382866278
Therefore, the lowest common multiple of 131,978,249,682,231 is 25382866278.
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 978 x 249 x 682 x 231 = 5025807523044
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
978 : 1, 2, 3, 6, 163, 326, 489, 978
249 : 1, 3, 83, 249
682 : 1, 2, 11, 22, 31, 62, 341, 682
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,978,249,682,231, is 1.
Now, the common factors can be found like this.
131:131
978:2x 3x 163
249:3x 83
682:2x 11x 31
231:3x 7x 11
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 11 = 198
Therefore, the value for common factors is 198.
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 = 5025807523044/(1x198)
LCM = 5025807523044/198
LCM = 25382866278
Thus, we can understand that the LCM of 131,978,249,682,231 is 25382866278.
