The LCM of 447,275,212,855,689 is 19310534100.
Find LCM of 447,275,212,855,689 with Prime Factorization
| 3 | 447, 275, 212, 855, 689 |
| 5 | 149, 275, 212, 285, 689 |
| 53 | 149, 55, 212, 57, 689 |
| 149, 55, 4, 57, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 53 x 149 x 55 x 4 x 57 x 13 = 19310534100
Therefore, the lowest common multiple of 447,275,212,855,689 is 19310534100.
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.
447 x 275 x 212 x 855 x 689 = 15351874609500
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.
447 : 1, 3, 149, 447
275 : 1, 5, 11, 25, 55, 275
212 : 1, 2, 4, 53, 106, 212
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,275,212,855,689, is 1.
Now, the common factors can be found like this.
447:3x 149
275:5x 5x 11
212:2x 2x 53
855:3x 3x 5x 19
689:13x 53
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 53 = 795
Therefore, the value for common factors is 795.
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 = 15351874609500/(1x795)
LCM = 15351874609500/795
LCM = 19310534100
Thus, we can understand that the LCM of 447,275,212,855,689 is 19310534100.
