Given numbers are 416,636,823,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 416,636,823,720 is 816547680.
Find LCM of 416,636,823,720 with Prime Factorization
| 2 | 416, 636, 823, 720 |
| 2 | 208, 318, 823, 360 |
| 2 | 104, 159, 823, 180 |
| 2 | 52, 159, 823, 90 |
| 3 | 26, 159, 823, 45 |
| 26, 53, 823, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 26 x 53 x 823 x 15 = 816547680
Therefore, the lowest common multiple of 416,636,823,720 is 816547680.
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.
416 x 636 x 823 x 720 = 156777154560
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.
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
823 : 1, 823
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,636,823,720, is 1.
Now, the common factors can be found like this.
416:2x 2x 2x 2x 2x 13
636:2x 2x 3x 53
823:823
720:2x 2x 2x 2x 3x 3x 5
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 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 156777154560/(1x192)
LCM = 156777154560/192
LCM = 816547680
Thus, we can understand that the LCM of 416,636,823,720 is 816547680.
