Given numbers are 411,489,618,420,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 411,489,618,420,556 is 134279429340.
Find LCM of 411,489,618,420,556 with Prime Factorization
| 2 | 411, 489, 618, 420, 556 |
| 2 | 411, 489, 309, 210, 278 |
| 3 | 411, 489, 309, 105, 139 |
| 137, 163, 103, 35, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 137 x 163 x 103 x 35 x 139 = 134279429340
Therefore, the lowest common multiple of 411,489,618,420,556 is 134279429340.
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.
411 x 489 x 618 x 420 x 556 = 29004356737440
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.
411 : 1, 3, 137, 411
489 : 1, 3, 163, 489
618 : 1, 2, 3, 6, 103, 206, 309, 618
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
556 : 1, 2, 4, 139, 278, 556
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,489,618,420,556, is 1.
Now, the common factors can be found like this.
411:3x 137
489:3x 163
618:2x 3x 103
420:2x 2x 3x 5x 7
556:2x 2x 139
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 29004356737440/(1x216)
LCM = 29004356737440/216
LCM = 134279429340
Thus, we can understand that the LCM of 411,489,618,420,556 is 134279429340.
