Given numbers are 670,692,324,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 670,692,324,621 is 431880660.
Find LCM of 670,692,324,621 with Prime Factorization
| 2 | 670, 692, 324, 621 |
| 2 | 335, 346, 162, 621 |
| 3 | 335, 173, 81, 621 |
| 3 | 335, 173, 27, 207 |
| 3 | 335, 173, 9, 69 |
| 335, 173, 3, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 335 x 173 x 3 x 23 = 431880660
Therefore, the lowest common multiple of 670,692,324,621 is 431880660.
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.
670 x 692 x 324 x 621 = 93286222560
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.
670 : 1, 2, 5, 10, 67, 134, 335, 670
692 : 1, 2, 4, 173, 346, 692
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,692,324,621, is 1.
Now, the common factors can be found like this.
670:2x 5x 67
692:2x 2x 173
324:2x 2x 3x 3x 3x 3
621:3x 3x 3x 23
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 3 = 216
Therefore, the value for common factors is 216.
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 = 93286222560/(1x216)
LCM = 93286222560/216
LCM = 431880660
Thus, we can understand that the LCM of 670,692,324,621 is 431880660.
