Given numbers are 668,533,579,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,533,579,189 is 12987416988.
Find LCM of 668,533,579,189 with Prime Factorization
| 3 | 668, 533, 579, 189 |
| 668, 533, 193, 63 |
Multiply the prime numbers at the bottom and the left side.
3 x 668 x 533 x 193 x 63 = 12987416988
Therefore, the lowest common multiple of 668,533,579,189 is 12987416988.
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 533 x 579 x 189 = 38962250964
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
533 : 1, 13, 41, 533
579 : 1, 3, 193, 579
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,533,579,189, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
533:13x 41
579:3x 193
189:3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 38962250964/(1x3)
LCM = 38962250964/3
LCM = 12987416988
Thus, we can understand that the LCM of 668,533,579,189 is 12987416988.
