The LCM of 489,770,165,497,581 is 2218891290.
Find LCM of 489,770,165,497,581 with Prime Factorization
| 3 | 489, 770, 165, 497, 581 |
| 5 | 163, 770, 55, 497, 581 |
| 7 | 163, 154, 11, 497, 581 |
| 11 | 163, 22, 11, 71, 83 |
| 163, 2, 1, 71, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 11 x 163 x 2 x 1 x 71 x 83 = 2218891290
Therefore, the lowest common multiple of 489,770,165,497,581 is 2218891290.
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.
489 x 770 x 165 x 497 x 581 = 17939736079650
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.
489 : 1, 3, 163, 489
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
165 : 1, 3, 5, 11, 15, 33, 55, 165
497 : 1, 7, 71, 497
581 : 1, 7, 83, 581
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,770,165,497,581, is 1.
Now, the common factors can be found like this.
489:3x 163
770:2x 5x 7x 11
165:3x 5x 11
497:7x 71
581:7x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 7x 11 = 8085
Therefore, the value for common factors is 8085.
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 = 17939736079650/(1x8085)
LCM = 17939736079650/8085
LCM = 2218891290
Thus, we can understand that the LCM of 489,770,165,497,581 is 2218891290.
