The LCM of 423,747,738,492 is 5757876.
Find LCM of 423,747,738,492 with Prime Factorization
| 2 | 423, 747, 738, 492 |
| 3 | 423, 747, 369, 246 |
| 3 | 141, 249, 123, 82 |
| 41 | 47, 83, 41, 82 |
| 47, 83, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 41 x 47 x 83 x 1 x 2 = 5757876
Therefore, the lowest common multiple of 423,747,738,492 is 5757876.
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.
423 x 747 x 738 x 492 = 114731437176
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.
423 : 1, 3, 9, 47, 141, 423
747 : 1, 3, 9, 83, 249, 747
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,747,738,492, is 3.
Now, the common factors can be found like this.
423:3x 3x 47
747:3x 3x 83
738:2x 3x 3x 41
492:2x 2x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 41 = 6642
Therefore, the value for common factors is 6642.
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 = 114731437176/(3x6642)
LCM = 114731437176/19926
LCM = 5757876
Thus, we can understand that the LCM of 423,747,738,492 is 5757876.
