Given numbers are 185,212,489,630
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 185,212,489,630 is 402750180.
Find LCM of 185,212,489,630 with Prime Factorization
| 2 | 185, 212, 489, 630 |
| 3 | 185, 106, 489, 315 |
| 5 | 185, 106, 163, 105 |
| 37, 106, 163, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 37 x 106 x 163 x 21 = 402750180
Therefore, the lowest common multiple of 185,212,489,630 is 402750180.
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.
185 x 212 x 489 x 630 = 12082505400
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.
185 : 1, 5, 37, 185
212 : 1, 2, 4, 53, 106, 212
489 : 1, 3, 163, 489
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 185,212,489,630, is 1.
Now, the common factors can be found like this.
185:5x 37
212:2x 2x 53
489:3x 163
630:2x 3x 3x 5x 7
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 5 = 30
Therefore, the value for common factors is 30.
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 = 12082505400/(1x30)
LCM = 12082505400/30
LCM = 402750180
Thus, we can understand that the LCM of 185,212,489,630 is 402750180.
