Given numbers are 832,867,917,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 832,867,917,420 is 3307362240.
Find LCM of 832,867,917,420 with Prime Factorization
| 2 | 832, 867, 917, 420 |
| 2 | 416, 867, 917, 210 |
| 3 | 208, 867, 917, 105 |
| 7 | 208, 289, 917, 35 |
| 208, 289, 131, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 208 x 289 x 131 x 5 = 3307362240
Therefore, the lowest common multiple of 832,867,917,420 is 3307362240.
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.
832 x 867 x 917 x 420 = 277818428160
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.
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
867 : 1, 3, 17, 51, 289, 867
917 : 1, 7, 131, 917
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 832,867,917,420, is 1.
Now, the common factors can be found like this.
832:2x 2x 2x 2x 2x 2x 13
867:3x 17x 17
917:7x 131
420:2x 2x 3x 5x 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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 277818428160/(1x84)
LCM = 277818428160/84
LCM = 3307362240
Thus, we can understand that the LCM of 832,867,917,420 is 3307362240.
