Given numbers are 240,185,430,990,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 240,185,430,990,418 is 239413680.
Find LCM of 240,185,430,990,418 with Prime Factorization
| 2 | 240, 185, 430, 990, 418 |
| 3 | 120, 185, 215, 495, 209 |
| 5 | 40, 185, 215, 165, 209 |
| 11 | 8, 37, 43, 33, 209 |
| 8, 37, 43, 3, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 8 x 37 x 43 x 3 x 19 = 239413680
Therefore, the lowest common multiple of 240,185,430,990,418 is 239413680.
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.
240 x 185 x 430 x 990 x 418 = 7900651440000
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.
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
185 : 1, 5, 37, 185
430 : 1, 2, 5, 10, 43, 86, 215, 430
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,185,430,990,418, is 1.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
185:5x 37
430:2x 5x 43
990:2x 3x 3x 5x 11
418:2x 11x 19
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 5x 5x 5x 11 = 33000
Therefore, the value for common factors is 33000.
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 = 7900651440000/(1x33000)
LCM = 7900651440000/33000
LCM = 239413680
Thus, we can understand that the LCM of 240,185,430,990,418 is 239413680.
