Given numbers are 704,123,589,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 704,123,589,820 is 255013440.
Find LCM of 704,123,589,820 with Prime Factorization
| 2 | 704, 123, 589, 820 |
| 2 | 352, 123, 589, 410 |
| 41 | 176, 123, 589, 205 |
| 176, 3, 589, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 41 x 176 x 3 x 589 x 5 = 255013440
Therefore, the lowest common multiple of 704,123,589,820 is 255013440.
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.
704 x 123 x 589 x 820 = 41822204160
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.
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
123 : 1, 3, 41, 123
589 : 1, 19, 31, 589
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,123,589,820, is 1.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
123:3x 41
589:19x 31
820:2x 2x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 41 = 164
Therefore, the value for common factors is 164.
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 = 41822204160/(1x164)
LCM = 41822204160/164
LCM = 255013440
Thus, we can understand that the LCM of 704,123,589,820 is 255013440.
