Given numbers are 404,946,781,149
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 404,946,781,149 is 2021562268.
Find LCM of 404,946,781,149 with Prime Factorization
| 2 | 404, 946, 781, 149 |
| 11 | 202, 473, 781, 149 |
| 202, 43, 71, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 202 x 43 x 71 x 149 = 2021562268
Therefore, the lowest common multiple of 404,946,781,149 is 2021562268.
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.
404 x 946 x 781 x 149 = 44474369896
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.
404 : 1, 2, 4, 101, 202, 404
946 : 1, 2, 11, 22, 43, 86, 473, 946
781 : 1, 11, 71, 781
149 : 1, 149
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 404,946,781,149, is 1.
Now, the common factors can be found like this.
404:2x 2x 101
946:2x 11x 43
781:11x 71
149:149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 44474369896/(1x22)
LCM = 44474369896/22
LCM = 2021562268
Thus, we can understand that the LCM of 404,946,781,149 is 2021562268.
