The LCM of 428,833,160,392 is 14260960.
Find LCM of 428,833,160,392 with Prime Factorization
| 2 | 428, 833, 160, 392 |
| 2 | 214, 833, 80, 196 |
| 2 | 107, 833, 40, 98 |
| 7 | 107, 833, 20, 49 |
| 7 | 107, 119, 20, 7 |
| 107, 17, 20, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 107 x 17 x 20 x 1 = 14260960
Therefore, the lowest common multiple of 428,833,160,392 is 14260960.
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 833 x 160 x 392 = 22361185280
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
833 : 1, 7, 17, 49, 119, 833
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,833,160,392, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
833:7x 7x 17
160:2x 2x 2x 2x 2x 5
392:2x 2x 2x 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 2x 2x 2x 7x 7 = 1568
Therefore, the value for common factors is 1568.
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 = 22361185280/(1x1568)
LCM = 22361185280/1568
LCM = 14260960
Thus, we can understand that the LCM of 428,833,160,392 is 14260960.
