Given numbers are 792,706,420,278,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 792,706,420,278,162 is 12241235160.
Find LCM of 792,706,420,278,162 with Prime Factorization
| 2 | 792, 706, 420, 278, 162 |
| 2 | 396, 353, 210, 139, 81 |
| 3 | 198, 353, 105, 139, 81 |
| 3 | 66, 353, 35, 139, 27 |
| 22, 353, 35, 139, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 22 x 353 x 35 x 139 x 9 = 12241235160
Therefore, the lowest common multiple of 792,706,420,278,162 is 12241235160.
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.
792 x 706 x 420 x 278 x 162 = 10576427178240
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.
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
706 : 1, 2, 353, 706
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
278 : 1, 2, 139, 278
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,706,420,278,162, is 2.
Now, the common factors can be found like this.
792:2x 2x 2x 3x 3x 11
706:2x 353
420:2x 2x 3x 5x 7
278:2x 139
162:2x 3x 3x 3x 3
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 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 10576427178240/(2x432)
LCM = 10576427178240/864
LCM = 12241235160
Thus, we can understand that the LCM of 792,706,420,278,162 is 12241235160.
