Given numbers are 684,328,518,944
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,328,518,944 is 1714161456.
Find LCM of 684,328,518,944 with Prime Factorization
| 2 | 684, 328, 518, 944 |
| 2 | 342, 164, 259, 472 |
| 2 | 171, 82, 259, 236 |
| 171, 41, 259, 118 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 171 x 41 x 259 x 118 = 1714161456
Therefore, the lowest common multiple of 684,328,518,944 is 1714161456.
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 328 x 518 x 944 = 109706333184
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
328 : 1, 2, 4, 8, 41, 82, 164, 328
518 : 1, 2, 7, 14, 37, 74, 259, 518
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,328,518,944, is 2.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
328:2x 2x 2x 41
518:2x 7x 37
944:2x 2x 2x 2x 59
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 2 = 32
Therefore, the value for common factors is 32.
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 = 109706333184/(2x32)
LCM = 109706333184/64
LCM = 1714161456
Thus, we can understand that the LCM of 684,328,518,944 is 1714161456.
