Find LCM of 684,672,399,968 with Prime Factorization
| 2 | 684, 672, 399, 968 |
| 2 | 342, 336, 399, 484 |
| 2 | 171, 168, 399, 242 |
| 3 | 171, 84, 399, 121 |
| 7 | 57, 28, 133, 121 |
| 19 | 57, 4, 19, 121 |
| 3, 4, 1, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 19 x 3 x 4 x 1 x 121 = 4634784
Therefore, the lowest common multiple of 684,672,399,968 is 4634784.
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 672 x 399 x 968 = 177530766336
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
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
399 : 1, 3, 7, 19, 21, 57, 133, 399
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,672,399,968, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
672:2x 2x 2x 2x 2x 3x 7
399:3x 7x 19
968:2x 2x 2x 11x 11
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 3x 3x 7x 19 = 38304
Therefore, the value for common factors is 38304.
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 = 177530766336/(1x38304)
LCM = 177530766336/38304
LCM = 4634784
Thus, we can understand that the LCM of 684,672,399,968 is 4634784.
