| 3 | 249, 31, 1, 349, 3 |
| 83, 31, 1, 349, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 83 x 31 x 1 x 349 x 1 = 689646336
Therefore, the lowest common multiple of 249,496,256,698,768 is 689646336.
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.
249 x 496 x 256 x 698 x 768 = 16948748353536
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.
249 : 1, 3, 83, 249
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
698 : 1, 2, 349, 698
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 249,496,256,698,768, is 1.
Now, the common factors can be found like this.
249:3x 83
496:2x 2x 2x 2x 31
256:2x 2x 2x 2x 2x 2x 2x 2
698:2x 349
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 2x 2x 2x 2x 2x 2x 2x 2x 2x 3 = 24576
Therefore, the value for common factors is 24576.
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 = 16948748353536/(1x24576)
LCM = 16948748353536/24576
LCM = 689646336
Thus, we can understand that the LCM of 249,496,256,698,768 is 689646336.
