Given numbers are 382,646,573,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 382,646,573,154 is 28502166.
Find LCM of 382,646,573,154 with Prime Factorization
| 2 | 382, 646, 573, 154 |
| 191 | 191, 323, 573, 77 |
| 1, 323, 3, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 191 x 1 x 323 x 3 x 77 = 28502166
Therefore, the lowest common multiple of 382,646,573,154 is 28502166.
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.
382 x 646 x 573 x 154 = 21775654824
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.
382 : 1, 2, 191, 382
646 : 1, 2, 17, 19, 34, 38, 323, 646
573 : 1, 3, 191, 573
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,646,573,154, is 1.
Now, the common factors can be found like this.
382:2x 191
646:2x 17x 19
573:3x 191
154:2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 191 = 764
Therefore, the value for common factors is 764.
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 = 21775654824/(1x764)
LCM = 21775654824/764
LCM = 28502166
Thus, we can understand that the LCM of 382,646,573,154 is 28502166.
