Given numbers are 345,794,411,330,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 345,794,411,330,639 is 87929064630.
Find LCM of 345,794,411,330,639 with Prime Factorization
| 2 | 345, 794, 411, 330, 639 |
| 3 | 345, 397, 411, 165, 639 |
| 5 | 115, 397, 137, 55, 213 |
| 23, 397, 137, 11, 213 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 397 x 137 x 11 x 213 = 87929064630
Therefore, the lowest common multiple of 345,794,411,330,639 is 87929064630.
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.
345 x 794 x 411 x 330 x 639 = 23740847450100
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
794 : 1, 2, 397, 794
411 : 1, 3, 137, 411
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,794,411,330,639, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
794:2x 397
411:3x 137
330:2x 3x 5x 11
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 23740847450100/(1x270)
LCM = 23740847450100/270
LCM = 87929064630
Thus, we can understand that the LCM of 345,794,411,330,639 is 87929064630.
