Given numbers are 224,786,391,324
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 224,786,391,324 is 929353824.
Find LCM of 224,786,391,324 with Prime Factorization
| 2 | 224, 786, 391, 324 |
| 2 | 112, 393, 391, 162 |
| 3 | 56, 393, 391, 81 |
| 56, 131, 391, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 56 x 131 x 391 x 27 = 929353824
Therefore, the lowest common multiple of 224,786,391,324 is 929353824.
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.
224 x 786 x 391 x 324 = 22304491776
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.
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
786 : 1, 2, 3, 6, 131, 262, 393, 786
391 : 1, 17, 23, 391
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 224,786,391,324, is 1.
Now, the common factors can be found like this.
224:2x 2x 2x 2x 2x 7
786:2x 3x 131
391:17x 23
324:2x 2x 3x 3x 3x 3
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 3 = 24
Therefore, the value for common factors is 24.
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 = 22304491776/(1x24)
LCM = 22304491776/24
LCM = 929353824
Thus, we can understand that the LCM of 224,786,391,324 is 929353824.
