Given numbers are 376,476,238,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 376,476,238,642 is 14362824.
Find LCM of 376,476,238,642 with Prime Factorization
| 2 | 376, 476, 238, 642 |
| 2 | 188, 238, 119, 321 |
| 7 | 94, 119, 119, 321 |
| 17 | 94, 17, 17, 321 |
| 94, 1, 1, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 17 x 94 x 1 x 1 x 321 = 14362824
Therefore, the lowest common multiple of 376,476,238,642 is 14362824.
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 476 x 238 x 642 = 27346816896
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
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
238 : 1, 2, 7, 14, 17, 34, 119, 238
642 : 1, 2, 3, 6, 107, 214, 321, 642
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 376,476,238,642, is 2.
Now, the common factors can be found like this.
376:2x 2x 2x 47
476:2x 2x 7x 17
238:2x 7x 17
642:2x 3x 107
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 7x 17 = 952
Therefore, the value for common factors is 952.
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 = 27346816896/(2x952)
LCM = 27346816896/1904
LCM = 14362824
Thus, we can understand that the LCM of 376,476,238,642 is 14362824.
