Given numbers are 281,165,561,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,165,561,494 is 389373270.
Find LCM of 281,165,561,494 with Prime Factorization
| 3 | 281, 165, 561, 494 |
| 11 | 281, 55, 187, 494 |
| 281, 5, 17, 494 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 281 x 5 x 17 x 494 = 389373270
Therefore, the lowest common multiple of 281,165,561,494 is 389373270.
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.
281 x 165 x 561 x 494 = 12849317910
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.
281 : 1, 281
165 : 1, 3, 5, 11, 15, 33, 55, 165
561 : 1, 3, 11, 17, 33, 51, 187, 561
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,165,561,494, is 1.
Now, the common factors can be found like this.
281:281
165:3x 5x 11
561:3x 11x 17
494:2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 12849317910/(1x33)
LCM = 12849317910/33
LCM = 389373270
Thus, we can understand that the LCM of 281,165,561,494 is 389373270.
