Given numbers are 400,809,403,809,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,809,403,809,546 is 2738626800.
Find LCM of 400,809,403,809,546 with Prime Factorization
| 2 | 400, 809, 403, 809, 546 |
| 13 | 200, 809, 403, 809, 273 |
| 809 | 200, 809, 31, 809, 21 |
| 200, 1, 31, 1, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 809 x 200 x 1 x 31 x 1 x 21 = 2738626800
Therefore, the lowest common multiple of 400,809,403,809,546 is 2738626800.
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.
400 x 809 x 403 x 809 x 546 = 57604276111200
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
809 : 1, 809
403 : 1, 13, 31, 403
809 : 1, 809
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,809,403,809,546, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
809:809
403:13x 31
809:809
546:2x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 809 = 21034
Therefore, the value for common factors is 21034.
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 = 57604276111200/(1x21034)
LCM = 57604276111200/21034
LCM = 2738626800
Thus, we can understand that the LCM of 400,809,403,809,546 is 2738626800.
