Given numbers are 808,553,946,449,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,553,946,449,788 is 18694342707656.
Find LCM of 808,553,946,449,788 with Prime Factorization
| 2 | 808, 553, 946, 449, 788 |
| 2 | 404, 553, 473, 449, 394 |
| 202, 553, 473, 449, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 202 x 553 x 473 x 449 x 197 = 18694342707656
Therefore, the lowest common multiple of 808,553,946,449,788 is 18694342707656.
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.
808 x 553 x 946 x 449 x 788 = 149554741661248
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
553 : 1, 7, 79, 553
946 : 1, 2, 11, 22, 43, 86, 473, 946
449 : 1, 449
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,553,946,449,788, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
553:7x 79
946:2x 11x 43
449:449
788:2x 2x 197
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 2 = 8
Therefore, the value for common factors is 8.
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 = 149554741661248/(1x8)
LCM = 149554741661248/8
LCM = 18694342707656
Thus, we can understand that the LCM of 808,553,946,449,788 is 18694342707656.
