Given numbers are 131,162,561,726
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,162,561,726 is 43653654.
Find LCM of 131,162,561,726 with Prime Factorization
| 2 | 131, 162, 561, 726 |
| 3 | 131, 81, 561, 363 |
| 11 | 131, 27, 187, 121 |
| 131, 27, 17, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 131 x 27 x 17 x 11 = 43653654
Therefore, the lowest common multiple of 131,162,561,726 is 43653654.
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 162 x 561 x 726 = 8643423492
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
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
561 : 1, 3, 11, 17, 33, 51, 187, 561
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,162,561,726, is 1.
Now, the common factors can be found like this.
131:131
162:2x 3x 3x 3x 3
561:3x 11x 17
726:2x 3x 11x 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 = 8643423492/(1x198)
LCM = 8643423492/198
LCM = 43653654
Thus, we can understand that the LCM of 131,162,561,726 is 43653654.
