The LCM of 888,489,455,851,621 is 13632713640.
Find LCM of 888,489,455,851,621 with Prime Factorization
| 3 | 888, 489, 455, 851, 621 |
| 23 | 296, 163, 455, 851, 207 |
| 37 | 296, 163, 455, 37, 9 |
| 8, 163, 455, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 37 x 8 x 163 x 455 x 1 x 9 = 13632713640
Therefore, the lowest common multiple of 888,489,455,851,621 is 13632713640.
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.
888 x 489 x 455 x 851 x 621 = 104412953768760
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.
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
489 : 1, 3, 163, 489
455 : 1, 5, 7, 13, 35, 65, 91, 455
851 : 1, 23, 37, 851
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 888,489,455,851,621, is 1.
Now, the common factors can be found like this.
888:2x 2x 2x 3x 37
489:3x 163
455:5x 7x 13
851:23x 37
621:3x 3x 3x 23
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 23x 37 = 7659
Therefore, the value for common factors is 7659.
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 = 104412953768760/(1x7659)
LCM = 104412953768760/7659
LCM = 13632713640
Thus, we can understand that the LCM of 888,489,455,851,621 is 13632713640.
