Given numbers are 396,643,120,142,329
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,643,120,142,329 is 59478554520.
Find LCM of 396,643,120,142,329 with Prime Factorization
| 2 | 396, 643, 120, 142, 329 |
| 2 | 198, 643, 60, 71, 329 |
| 3 | 99, 643, 30, 71, 329 |
| 33, 643, 10, 71, 329 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 33 x 643 x 10 x 71 x 329 = 59478554520
Therefore, the lowest common multiple of 396,643,120,142,329 is 59478554520.
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.
396 x 643 x 120 x 142 x 329 = 1427485308480
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
643 : 1, 643
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
142 : 1, 2, 71, 142
329 : 1, 7, 47, 329
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,643,120,142,329, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
643:643
120:2x 2x 2x 3x 5
142:2x 71
329:7x 47
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 3 = 24
Therefore, the value for common factors is 24.
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 = 1427485308480/(1x24)
LCM = 1427485308480/24
LCM = 59478554520
Thus, we can understand that the LCM of 396,643,120,142,329 is 59478554520.
