Find LCM of 181,539,858,252,431 with Prime Factorization
| 2 | 181, 539, 858, 252, 431 |
| 3 | 181, 539, 429, 126, 431 |
| 7 | 181, 539, 143, 42, 431 |
| 11 | 181, 77, 143, 6, 431 |
| 181, 7, 13, 6, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 181 x 7 x 13 x 6 x 431 = 19678430772
Therefore, the lowest common multiple of 181,539,858,252,431 is 19678430772.
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.
181 x 539 x 858 x 252 x 431 = 9091435016664
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.
181 : 1, 181
539 : 1, 7, 11, 49, 77, 539
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,539,858,252,431, is 1.
Now, the common factors can be found like this.
181:181
539:7x 7x 11
858:2x 3x 11x 13
252:2x 2x 3x 3x 7
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 11 = 462
Therefore, the value for common factors is 462.
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 = 9091435016664/(1x462)
LCM = 9091435016664/462
LCM = 19678430772
Thus, we can understand that the LCM of 181,539,858,252,431 is 19678430772.
