Find LCM of 409,993,592,861,768 with Prime Factorization
| 2 | 409, 993, 592, 861, 768 |
| 2 | 409, 993, 296, 861, 384 |
| 2 | 409, 993, 148, 861, 192 |
| 2 | 409, 993, 74, 861, 96 |
| 3 | 409, 993, 37, 861, 48 |
| 409, 331, 37, 287, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 409 x 331 x 37 x 287 x 16 = 1104068813568
Therefore, the lowest common multiple of 409,993,592,861,768 is 1104068813568.
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.
409 x 993 x 592 x 861 x 768 = 158985909153792
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.
409 : 1, 409
993 : 1, 3, 331, 993
592 : 1, 2, 4, 8, 16, 37, 74, 148, 296, 592
861 : 1, 3, 7, 21, 41, 123, 287, 861
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,993,592,861,768, is 1.
Now, the common factors can be found like this.
409:409
993:3x 331
592:2x 2x 2x 2x 37
861:3x 7x 41
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 = 158985909153792/(1x144)
LCM = 158985909153792/144
LCM = 1104068813568
Thus, we can understand that the LCM of 409,993,592,861,768 is 1104068813568.
