Given numbers are 920,688,667,924
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,688,667,924 is 530024880.
Find LCM of 920,688,667,924 with Prime Factorization
| 2 | 920, 688, 667, 924 |
| 2 | 460, 344, 667, 462 |
| 2 | 230, 172, 667, 231 |
| 23 | 115, 86, 667, 231 |
| 5, 86, 29, 231 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 23 x 5 x 86 x 29 x 231 = 530024880
Therefore, the lowest common multiple of 920,688,667,924 is 530024880.
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.
920 x 688 x 667 x 924 = 390098311680
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
667 : 1, 23, 29, 667
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,688,667,924, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
688:2x 2x 2x 2x 43
667:23x 29
924:2x 2x 3x 7x 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 23 = 736
Therefore, the value for common factors is 736.
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 = 390098311680/(1x736)
LCM = 390098311680/736
LCM = 530024880
Thus, we can understand that the LCM of 920,688,667,924 is 530024880.
