Find LCM of 768,493,342,979,264 with Prime Factorization
| 2 | 768, 493, 342, 979, 264 |
| 2 | 384, 493, 171, 979, 132 |
| 2 | 192, 493, 171, 979, 66 |
| 3 | 96, 493, 171, 979, 33 |
| 11 | 32, 493, 57, 979, 11 |
| 32, 493, 57, 89, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 32 x 493 x 57 x 89 x 1 = 21128355072
Therefore, the lowest common multiple of 768,493,342,979,264 is 21128355072.
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.
768 x 493 x 342 x 979 x 264 = 33467314434048
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
493 : 1, 17, 29, 493
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
979 : 1, 11, 89, 979
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,493,342,979,264, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
493:17x 29
342:2x 3x 3x 19
979:11x 89
264:2x 2x 2x 3x 11
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 3x 11 = 1584
Therefore, the value for common factors is 1584.
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 = 33467314434048/(1x1584)
LCM = 33467314434048/1584
LCM = 21128355072
Thus, we can understand that the LCM of 768,493,342,979,264 is 21128355072.
