The LCM of 585,421,178,855,423 is 39147985890.
Find LCM of 585,421,178,855,423 with Prime Factorization
| 3 | 585, 421, 178, 855, 423 |
| 3 | 195, 421, 178, 285, 141 |
| 5 | 65, 421, 178, 95, 47 |
| 13, 421, 178, 19, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 13 x 421 x 178 x 19 x 47 = 39147985890
Therefore, the lowest common multiple of 585,421,178,855,423 is 39147985890.
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.
585 x 421 x 178 x 855 x 423 = 15854934285450
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.
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
421 : 1, 421
178 : 1, 2, 89, 178
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 585,421,178,855,423, is 1.
Now, the common factors can be found like this.
585:3x 3x 5x 13
421:421
178:2x 89
855:3x 3x 5x 19
423:3x 3x 47
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 3x 3x 5 = 405
Therefore, the value for common factors is 405.
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 = 15854934285450/(1x405)
LCM = 15854934285450/405
LCM = 39147985890
Thus, we can understand that the LCM of 585,421,178,855,423 is 39147985890.
