Given numbers are 221,511,817,948,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,511,817,948,561 is 962135530356.
Find LCM of 221,511,817,948,561 with Prime Factorization
| 3 | 221, 511, 817, 948, 561 |
| 17 | 221, 511, 817, 316, 187 |
| 13, 511, 817, 316, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 13 x 511 x 817 x 316 x 11 = 962135530356
Therefore, the lowest common multiple of 221,511,817,948,561 is 962135530356.
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.
221 x 511 x 817 x 948 x 561 = 49068912048156
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.
221 : 1, 13, 17, 221
511 : 1, 7, 73, 511
817 : 1, 19, 43, 817
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,511,817,948,561, is 1.
Now, the common factors can be found like this.
221:13x 17
511:7x 73
817:19x 43
948:2x 2x 3x 79
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17 = 51
Therefore, the value for common factors is 51.
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 = 49068912048156/(1x51)
LCM = 49068912048156/51
LCM = 962135530356
Thus, we can understand that the LCM of 221,511,817,948,561 is 962135530356.
