Given numbers are 668,928,828,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,928,828,788 is 6319766304.
Find LCM of 668,928,828,788 with Prime Factorization
| 2 | 668, 928, 828, 788 |
| 2 | 334, 464, 414, 394 |
| 167, 232, 207, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 167 x 232 x 207 x 197 = 6319766304
Therefore, the lowest common multiple of 668,928,828,788 is 6319766304.
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.
668 x 928 x 828 x 788 = 404465043456
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.
668 : 1, 2, 4, 167, 334, 668
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
788 : 1, 2, 4, 197, 394, 788
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,928,828,788, is 4.
Now, the common factors can be found like this.
668:2x 2x 167
928:2x 2x 2x 2x 2x 29
828:2x 2x 3x 3x 23
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 404465043456/(4x16)
LCM = 404465043456/64
LCM = 6319766304
Thus, we can understand that the LCM of 668,928,828,788 is 6319766304.
