Given numbers are 384,358,454,681,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 384,358,454,681,639 is 3323454336.
Find LCM of 384,358,454,681,639 with Prime Factorization
| 2 | 384, 358, 454, 681, 639 |
| 3 | 192, 179, 227, 681, 639 |
| 227 | 64, 179, 227, 227, 213 |
| 64, 179, 1, 1, 213 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 227 x 64 x 179 x 1 x 1 x 213 = 3323454336
Therefore, the lowest common multiple of 384,358,454,681,639 is 3323454336.
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.
384 x 358 x 454 x 681 x 639 = 27159268833792
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.
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
358 : 1, 2, 179, 358
454 : 1, 2, 227, 454
681 : 1, 3, 227, 681
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 384,358,454,681,639, is 1.
Now, the common factors can be found like this.
384:2x 2x 2x 2x 2x 2x 2x 3
358:2x 179
454:2x 227
681:3x 227
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 2x 3x 3x 227 = 8172
Therefore, the value for common factors is 8172.
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 = 27159268833792/(1x8172)
LCM = 27159268833792/8172
LCM = 3323454336
Thus, we can understand that the LCM of 384,358,454,681,639 is 3323454336.
