Given numbers are 558,205,621,807,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 558,205,621,807,891 is 70065362070.
Find LCM of 558,205,621,807,891 with Prime Factorization
| 3 | 558, 205, 621, 807, 891 |
| 3 | 186, 205, 207, 269, 297 |
| 3 | 62, 205, 69, 269, 99 |
| 62, 205, 23, 269, 33 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 62 x 205 x 23 x 269 x 33 = 70065362070
Therefore, the lowest common multiple of 558,205,621,807,891 is 70065362070.
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.
558 x 205 x 621 x 807 x 891 = 51077648949030
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.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
205 : 1, 5, 41, 205
621 : 1, 3, 9, 23, 27, 69, 207, 621
807 : 1, 3, 269, 807
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,205,621,807,891, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
205:5x 41
621:3x 3x 3x 23
807:3x 269
891:3x 3x 3x 3x 11
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 3x 3x 3x 3 = 729
Therefore, the value for common factors is 729.
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 = 51077648949030/(1x729)
LCM = 51077648949030/729
LCM = 70065362070
Thus, we can understand that the LCM of 558,205,621,807,891 is 70065362070.
