Given numbers are 428,916,833,343
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,916,833,343 is 571507972.
Find LCM of 428,916,833,343 with Prime Factorization
| 2 | 428, 916, 833, 343 |
| 2 | 214, 458, 833, 343 |
| 7 | 107, 229, 833, 343 |
| 7 | 107, 229, 119, 49 |
| 107, 229, 17, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 107 x 229 x 17 x 7 = 571507972
Therefore, the lowest common multiple of 428,916,833,343 is 571507972.
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 916 x 833 x 343 = 112015562512
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
916 : 1, 2, 4, 229, 458, 916
833 : 1, 7, 17, 49, 119, 833
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,916,833,343, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
916:2x 2x 229
833:7x 7x 17
343:7x 7x 7
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 112015562512/(1x196)
LCM = 112015562512/196
LCM = 571507972
Thus, we can understand that the LCM of 428,916,833,343 is 571507972.
