Given numbers are 976,928,284,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 976,928,284,642 is 1290152928.
Find LCM of 976,928,284,642 with Prime Factorization
| 2 | 976, 928, 284, 642 |
| 2 | 488, 464, 142, 321 |
| 2 | 244, 232, 71, 321 |
| 2 | 122, 116, 71, 321 |
| 61, 58, 71, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 61 x 58 x 71 x 321 = 1290152928
Therefore, the lowest common multiple of 976,928,284,642 is 1290152928.
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.
976 x 928 x 284 x 642 = 165139574784
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.
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
284 : 1, 2, 4, 71, 142, 284
642 : 1, 2, 3, 6, 107, 214, 321, 642
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 976,928,284,642, is 2.
Now, the common factors can be found like this.
976:2x 2x 2x 2x 61
928:2x 2x 2x 2x 2x 29
284:2x 2x 71
642:2x 3x 107
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 2x 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 165139574784/(2x64)
LCM = 165139574784/128
LCM = 1290152928
Thus, we can understand that the LCM of 976,928,284,642 is 1290152928.
