Given numbers are 400,645,117,559
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,645,117,559 is 2012400.
Find LCM of 400,645,117,559 with Prime Factorization
| 3 | 400, 645, 117, 559 |
| 5 | 400, 215, 39, 559 |
| 13 | 80, 43, 39, 559 |
| 43 | 80, 43, 3, 43 |
| 80, 1, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 43 x 80 x 1 x 3 x 1 = 2012400
Therefore, the lowest common multiple of 400,645,117,559 is 2012400.
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 645 x 117 x 559 = 16873974000
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
645 : 1, 3, 5, 15, 43, 129, 215, 645
117 : 1, 3, 9, 13, 39, 117
559 : 1, 13, 43, 559
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,645,117,559, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
645:3x 5x 43
117:3x 3x 13
559:13x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13x 43 = 8385
Therefore, the value for common factors is 8385.
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 = 16873974000/(1x8385)
LCM = 16873974000/8385
LCM = 2012400
Thus, we can understand that the LCM of 400,645,117,559 is 2012400.
