| 29 | 116, 29, 1, 19, 899 |
| 4, 1, 1, 19, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 29 x 4 x 1 x 1 x 19 x 31 = 57392160
Therefore, the lowest common multiple of 928,435,168,665,899 is 57392160.
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.
928 x 435 x 168 x 665 x 899 = 40544117510400
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.
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
435 : 1, 3, 5, 15, 29, 87, 145, 435
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
665 : 1, 5, 7, 19, 35, 95, 133, 665
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 928,435,168,665,899, is 1.
Now, the common factors can be found like this.
928:2x 2x 2x 2x 2x 29
435:3x 5x 29
168:2x 2x 2x 3x 7
665:5x 7x 19
899:29x 31
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 3x 5x 7x 29x 29 = 706440
Therefore, the value for common factors is 706440.
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 = 40544117510400/(1x706440)
LCM = 40544117510400/706440
LCM = 57392160
Thus, we can understand that the LCM of 928,435,168,665,899 is 57392160.
