Given numbers are 155,651,540,561,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,651,540,561,811 is 17771167260.
Find LCM of 155,651,540,561,811 with Prime Factorization
| 3 | 155, 651, 540, 561, 811 |
| 5 | 155, 217, 180, 187, 811 |
| 31 | 31, 217, 36, 187, 811 |
| 1, 7, 36, 187, 811 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 31 x 1 x 7 x 36 x 187 x 811 = 17771167260
Therefore, the lowest common multiple of 155,651,540,561,811 is 17771167260.
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.
155 x 651 x 540 x 561 x 811 = 24790778327700
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.
155 : 1, 5, 31, 155
651 : 1, 3, 7, 21, 31, 93, 217, 651
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
561 : 1, 3, 11, 17, 33, 51, 187, 561
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,651,540,561,811, is 1.
Now, the common factors can be found like this.
155:5x 31
651:3x 7x 31
540:2x 2x 3x 3x 3x 5
561:3x 11x 17
811:811
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 31 = 1395
Therefore, the value for common factors is 1395.
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 = 24790778327700/(1x1395)
LCM = 24790778327700/1395
LCM = 17771167260
Thus, we can understand that the LCM of 155,651,540,561,811 is 17771167260.
