Find LCM of 846,456,216,305 with Prime Factorization
| 2 | 846, 456, 216, 305 |
| 2 | 423, 228, 108, 305 |
| 2 | 423, 114, 54, 305 |
| 3 | 423, 57, 27, 305 |
| 3 | 141, 19, 9, 305 |
| 47, 19, 3, 305 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 47 x 19 x 3 x 305 = 58830840
Therefore, the lowest common multiple of 846,456,216,305 is 58830840.
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.
846 x 456 x 216 x 305 = 25414922880
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.
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 846,456,216,305, is 1.
Now, the common factors can be found like this.
846:2x 3x 3x 47
456:2x 2x 2x 3x 19
216:2x 2x 2x 3x 3x 3
305:5x 61
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 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 25414922880/(1x432)
LCM = 25414922880/432
LCM = 58830840
Thus, we can understand that the LCM of 846,456,216,305 is 58830840.
