Given numbers are 821,165,141,578,589
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,165,141,578,589 is 2167544849910.
Find LCM of 821,165,141,578,589 with Prime Factorization
| 3 | 821, 165, 141, 578, 589 |
| 821, 55, 47, 578, 589 |
Multiply the prime numbers at the bottom and the left side.
3 x 821 x 55 x 47 x 578 x 589 = 2167544849910
Therefore, the lowest common multiple of 821,165,141,578,589 is 2167544849910.
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.
821 x 165 x 141 x 578 x 589 = 6502634549730
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.
821 : 1, 821
165 : 1, 3, 5, 11, 15, 33, 55, 165
141 : 1, 3, 47, 141
578 : 1, 2, 17, 34, 289, 578
589 : 1, 19, 31, 589
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,165,141,578,589, is 1.
Now, the common factors can be found like this.
821:821
165:3x 5x 11
141:3x 47
578:2x 17x 17
589:19x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 6502634549730/(1x3)
LCM = 6502634549730/3
LCM = 2167544849910
Thus, we can understand that the LCM of 821,165,141,578,589 is 2167544849910.
