Given numbers are 376,642,384,278,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 376,642,384,278,644 is 43216892544.
Find LCM of 376,642,384,278,644 with Prime Factorization
| 2 | 376, 642, 384, 278, 644 |
| 2 | 188, 321, 192, 139, 322 |
| 2 | 94, 321, 96, 139, 161 |
| 3 | 47, 321, 48, 139, 161 |
| 47, 107, 16, 139, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 47 x 107 x 16 x 139 x 161 = 43216892544
Therefore, the lowest common multiple of 376,642,384,278,644 is 43216892544.
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.
376 x 642 x 384 x 278 x 644 = 16595286736896
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.
376 : 1, 2, 4, 8, 47, 94, 188, 376
642 : 1, 2, 3, 6, 107, 214, 321, 642
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
278 : 1, 2, 139, 278
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 376,642,384,278,644, is 2.
Now, the common factors can be found like this.
376:2x 2x 2x 47
642:2x 3x 107
384:2x 2x 2x 2x 2x 2x 2x 3
278:2x 139
644:2x 2x 7x 23
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 3 = 192
Therefore, the value for common factors is 192.
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 = 16595286736896/(2x192)
LCM = 16595286736896/384
LCM = 43216892544
Thus, we can understand that the LCM of 376,642,384,278,644 is 43216892544.
