Given numbers are 728,341,833,396
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 728,341,833,396 is 265873608.
Find LCM of 728,341,833,396 with Prime Factorization
| 2 | 728, 341, 833, 396 |
| 2 | 364, 341, 833, 198 |
| 7 | 182, 341, 833, 99 |
| 11 | 26, 341, 119, 99 |
| 26, 31, 119, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 26 x 31 x 119 x 9 = 265873608
Therefore, the lowest common multiple of 728,341,833,396 is 265873608.
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.
728 x 341 x 833 x 396 = 81889071264
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
341 : 1, 11, 31, 341
833 : 1, 7, 17, 49, 119, 833
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,341,833,396, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
341:11x 31
833:7x 7x 17
396:2x 2x 3x 3x 11
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 11 = 308
Therefore, the value for common factors is 308.
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 = 81889071264/(1x308)
LCM = 81889071264/308
LCM = 265873608
Thus, we can understand that the LCM of 728,341,833,396 is 265873608.
