Given numbers are 817,649,495,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 817,649,495,915 is 1455489585.
Find LCM of 817,649,495,915 with Prime Factorization
| 3 | 817, 649, 495, 915 |
| 5 | 817, 649, 165, 305 |
| 11 | 817, 649, 33, 61 |
| 817, 59, 3, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 817 x 59 x 3 x 61 = 1455489585
Therefore, the lowest common multiple of 817,649,495,915 is 1455489585.
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.
817 x 649 x 495 x 915 = 240155781525
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.
817 : 1, 19, 43, 817
649 : 1, 11, 59, 649
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,649,495,915, is 1.
Now, the common factors can be found like this.
817:19x 43
649:11x 59
495:3x 3x 5x 11
915:3x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 240155781525/(1x165)
LCM = 240155781525/165
LCM = 1455489585
Thus, we can understand that the LCM of 817,649,495,915 is 1455489585.
