Given numbers are 800,420,417,460,408
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 800,420,417,460,408 is 913063200.
Find LCM of 800,420,417,460,408 with Prime Factorization
| 2 | 800, 420, 417, 460, 408 |
| 2 | 400, 210, 417, 230, 204 |
| 2 | 200, 105, 417, 115, 102 |
| 3 | 100, 105, 417, 115, 51 |
| 5 | 100, 35, 139, 115, 17 |
| 20, 7, 139, 23, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 20 x 7 x 139 x 23 x 17 = 913063200
Therefore, the lowest common multiple of 800,420,417,460,408 is 913063200.
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.
800 x 420 x 417 x 460 x 408 = 26296220160000
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.
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
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
417 : 1, 3, 139, 417
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 800,420,417,460,408, is 1.
Now, the common factors can be found like this.
800:2x 2x 2x 2x 2x 5x 5
420:2x 2x 3x 5x 7
417:3x 139
460:2x 2x 5x 23
408:2x 2x 2x 3x 17
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 2x 3x 3x 5x 5 = 28800
Therefore, the value for common factors is 28800.
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 = 26296220160000/(1x28800)
LCM = 26296220160000/28800
LCM = 913063200
Thus, we can understand that the LCM of 800,420,417,460,408 is 913063200.
