| 11 | 209, 11, 103, 1, 4 |
| 19, 1, 103, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 5 x 11 x 19 x 1 x 103 x 1 x 4 = 61997760
Therefore, the lowest common multiple of 418,198,515,240,576 is 61997760.
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.
418 x 198 x 515 x 240 x 576 = 5892267110400
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
515 : 1, 5, 103, 515
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,198,515,240,576, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
198:2x 3x 3x 11
515:5x 103
240:2x 2x 2x 2x 3x 5
576:2x 2x 2x 2x 2x 2x 3x 3
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 3x 3x 3x 5x 11 = 95040
Therefore, the value for common factors is 95040.
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 = 5892267110400/(1x95040)
LCM = 5892267110400/95040
LCM = 61997760
Thus, we can understand that the LCM of 418,198,515,240,576 is 61997760.
