Given numbers are 422,654,849,581
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,654,849,581 is 22689387462.
Find LCM of 422,654,849,581 with Prime Factorization
| 2 | 422, 654, 849, 581 |
| 3 | 211, 327, 849, 581 |
| 211, 109, 283, 581 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 211 x 109 x 283 x 581 = 22689387462
Therefore, the lowest common multiple of 422,654,849,581 is 22689387462.
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.
422 x 654 x 849 x 581 = 136136324772
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.
422 : 1, 2, 211, 422
654 : 1, 2, 3, 6, 109, 218, 327, 654
849 : 1, 3, 283, 849
581 : 1, 7, 83, 581
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,654,849,581, is 1.
Now, the common factors can be found like this.
422:2x 211
654:2x 3x 109
849:3x 283
581:7x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 136136324772/(1x6)
LCM = 136136324772/6
LCM = 22689387462
Thus, we can understand that the LCM of 422,654,849,581 is 22689387462.
