Given numbers are 492,328,574,181
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 492,328,574,181 is 1246728.
Find LCM of 492,328,574,181 with Prime Factorization
| 2 | 492, 328, 574, 181 |
| 2 | 246, 164, 287, 181 |
| 41 | 123, 82, 287, 181 |
| 3, 2, 7, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 41 x 3 x 2 x 7 x 181 = 1246728
Therefore, the lowest common multiple of 492,328,574,181 is 1246728.
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.
492 x 328 x 574 x 181 = 16765998144
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.
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
328 : 1, 2, 4, 8, 41, 82, 164, 328
574 : 1, 2, 7, 14, 41, 82, 287, 574
181 : 1, 181
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,328,574,181, is 1.
Now, the common factors can be found like this.
492:2x 2x 3x 41
328:2x 2x 2x 41
574:2x 7x 41
181:181
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 41x 41 = 13448
Therefore, the value for common factors is 13448.
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 = 16765998144/(1x13448)
LCM = 16765998144/13448
LCM = 1246728
Thus, we can understand that the LCM of 492,328,574,181 is 1246728.
