Given numbers are 668,172,565,543
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,172,565,543 is 8812379580.
Find LCM of 668,172,565,543 with Prime Factorization
| 2 | 668, 172, 565, 543 |
| 2 | 334, 86, 565, 543 |
| 167, 43, 565, 543 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 167 x 43 x 565 x 543 = 8812379580
Therefore, the lowest common multiple of 668,172,565,543 is 8812379580.
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 172 x 565 x 543 = 35249518320
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
172 : 1, 2, 4, 43, 86, 172
565 : 1, 5, 113, 565
543 : 1, 3, 181, 543
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,172,565,543, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
172:2x 2x 43
565:5x 113
543:3x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 35249518320/(1x4)
LCM = 35249518320/4
LCM = 8812379580
Thus, we can understand that the LCM of 668,172,565,543 is 8812379580.
