Given numbers are 165,361,554,605
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,361,554,605 is 362989110.
Find LCM of 165,361,554,605 with Prime Factorization
| 5 | 165, 361, 554, 605 |
| 11 | 33, 361, 554, 121 |
| 3, 361, 554, 11 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 3 x 361 x 554 x 11 = 362989110
Therefore, the lowest common multiple of 165,361,554,605 is 362989110.
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.
165 x 361 x 554 x 605 = 19964401050
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
361 : 1, 19, 361
554 : 1, 2, 277, 554
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,361,554,605, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
361:19x 19
554:2x 277
605:5x 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.
5x 11 = 55
Therefore, the value for common factors is 55.
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 = 19964401050/(1x55)
LCM = 19964401050/55
LCM = 362989110
Thus, we can understand that the LCM of 165,361,554,605 is 362989110.
