Given numbers are 495,465,654,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 495,465,654,861 is 960075270.
Find LCM of 495,465,654,861 with Prime Factorization
| 3 | 495, 465, 654, 861 |
| 5 | 165, 155, 218, 287 |
| 33, 31, 218, 287 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 33 x 31 x 218 x 287 = 960075270
Therefore, the lowest common multiple of 495,465,654,861 is 960075270.
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 465 x 654 x 861 = 129610161450
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
465 : 1, 3, 5, 15, 31, 93, 155, 465
654 : 1, 2, 3, 6, 109, 218, 327, 654
861 : 1, 3, 7, 21, 41, 123, 287, 861
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,465,654,861, is 3.
Now, the common factors can be found like this.
495:3x 3x 5x 11
465:3x 5x 31
654:2x 3x 109
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 129610161450/(3x45)
LCM = 129610161450/135
LCM = 960075270
Thus, we can understand that the LCM of 495,465,654,861 is 960075270.
