Given numbers are 816,381,360,659
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,381,360,659 is 1024402320.
Find LCM of 816,381,360,659 with Prime Factorization
| 2 | 816, 381, 360, 659 |
| 2 | 408, 381, 180, 659 |
| 2 | 204, 381, 90, 659 |
| 3 | 102, 381, 45, 659 |
| 34, 127, 15, 659 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 34 x 127 x 15 x 659 = 1024402320
Therefore, the lowest common multiple of 816,381,360,659 is 1024402320.
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.
816 x 381 x 360 x 659 = 73756967040
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
381 : 1, 3, 127, 381
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
659 : 1, 659
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,381,360,659, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
381:3x 127
360:2x 2x 2x 3x 3x 5
659:659
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 73756967040/(1x72)
LCM = 73756967040/72
LCM = 1024402320
Thus, we can understand that the LCM of 816,381,360,659 is 1024402320.
