Given numbers are 684,246,842,456
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,246,842,456 is 23613048.
Find LCM of 684,246,842,456 with Prime Factorization
| 2 | 684, 246, 842, 456 |
| 2 | 342, 123, 421, 228 |
| 3 | 171, 123, 421, 114 |
| 19 | 57, 41, 421, 38 |
| 3, 41, 421, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 3 x 41 x 421 x 2 = 23613048
Therefore, the lowest common multiple of 684,246,842,456 is 23613048.
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.
684 x 246 x 842 x 456 = 64605299328
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
246 : 1, 2, 3, 6, 41, 82, 123, 246
842 : 1, 2, 421, 842
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,246,842,456, is 2.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
246:2x 3x 41
842:2x 421
456:2x 2x 2x 3x 19
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 3x 3x 19 = 1368
Therefore, the value for common factors is 1368.
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 = 64605299328/(2x1368)
LCM = 64605299328/2736
LCM = 23613048
Thus, we can understand that the LCM of 684,246,842,456 is 23613048.
