Given numbers are 428,776,164,436,436
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,776,164,436,436 is 371070008.
Find LCM of 428,776,164,436,436 with Prime Factorization
| 2 | 428, 776, 164, 436, 436 |
| 2 | 214, 388, 82, 218, 218 |
| 109 | 107, 194, 41, 109, 109 |
| 107, 194, 41, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 109 x 107 x 194 x 41 x 1 x 1 = 371070008
Therefore, the lowest common multiple of 428,776,164,436,436 is 371070008.
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.
428 x 776 x 164 x 436 x 436 = 10354337503232
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.
428 : 1, 2, 4, 107, 214, 428
776 : 1, 2, 4, 8, 97, 194, 388, 776
164 : 1, 2, 4, 41, 82, 164
436 : 1, 2, 4, 109, 218, 436
436 : 1, 2, 4, 109, 218, 436
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,776,164,436,436, is 4.
Now, the common factors can be found like this.
428:2x 2x 107
776:2x 2x 2x 97
164:2x 2x 41
436:2x 2x 109
436:2x 2x 109
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 2x 109 = 6976
Therefore, the value for common factors is 6976.
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 = 10354337503232/(4x6976)
LCM = 10354337503232/27904
LCM = 371070008
Thus, we can understand that the LCM of 428,776,164,436,436 is 371070008.
