Given numbers are 254,251,444,636,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 254,251,444,636,990 is 123771378060.
Find LCM of 254,251,444,636,990 with Prime Factorization
| 2 | 254, 251, 444, 636, 990 |
| 2 | 127, 251, 222, 318, 495 |
| 3 | 127, 251, 111, 159, 495 |
| 127, 251, 37, 53, 165 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 127 x 251 x 37 x 53 x 165 = 123771378060
Therefore, the lowest common multiple of 254,251,444,636,990 is 123771378060.
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.
254 x 251 x 444 x 636 x 990 = 17823078440640
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.
254 : 1, 2, 127, 254
251 : 1, 251
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,251,444,636,990, is 1.
Now, the common factors can be found like this.
254:2x 127
251:251
444:2x 2x 3x 37
636:2x 2x 3x 53
990:2x 3x 3x 5x 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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 17823078440640/(1x144)
LCM = 17823078440640/144
LCM = 123771378060
Thus, we can understand that the LCM of 254,251,444,636,990 is 123771378060.
