Given numbers are 495,361,489,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 495,361,489,989 is 28806884865.
Find LCM of 495,361,489,989 with Prime Factorization
| 3 | 495, 361, 489, 989 |
| 165, 361, 163, 989 |
Multiply the prime numbers at the bottom and the left side.
3 x 165 x 361 x 163 x 989 = 28806884865
Therefore, the lowest common multiple of 495,361,489,989 is 28806884865.
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.
495 x 361 x 489 x 989 = 86420654595
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.
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
361 : 1, 19, 361
489 : 1, 3, 163, 489
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,361,489,989, is 1.
Now, the common factors can be found like this.
495:3x 3x 5x 11
361:19x 19
489:3x 163
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 86420654595/(1x3)
LCM = 86420654595/3
LCM = 28806884865
Thus, we can understand that the LCM of 495,361,489,989 is 28806884865.
