Given numbers are 668,501,871,270,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,501,871,270,639 is 5576821380.
Find LCM of 668,501,871,270,639 with Prime Factorization
| 2 | 668, 501, 871, 270, 639 |
| 3 | 334, 501, 871, 135, 639 |
| 3 | 334, 167, 871, 45, 213 |
| 167 | 334, 167, 871, 15, 71 |
| 2, 1, 871, 15, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 167 x 2 x 1 x 871 x 15 x 71 = 5576821380
Therefore, the lowest common multiple of 668,501,871,270,639 is 5576821380.
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 501 x 871 x 270 x 639 = 50291775204840
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
501 : 1, 3, 167, 501
871 : 1, 13, 67, 871
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,501,871,270,639, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
501:3x 167
871:13x 67
270:2x 3x 3x 3x 5
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 167 = 9018
Therefore, the value for common factors is 9018.
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 = 50291775204840/(1x9018)
LCM = 50291775204840/9018
LCM = 5576821380
Thus, we can understand that the LCM of 668,501,871,270,639 is 5576821380.
