Given numbers are 689,804,180,349,133
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,804,180,349,133 is 385694634780.
Find LCM of 689,804,180,349,133 with Prime Factorization
| 2 | 689, 804, 180, 349, 133 |
| 2 | 689, 402, 90, 349, 133 |
| 3 | 689, 201, 45, 349, 133 |
| 689, 67, 15, 349, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 689 x 67 x 15 x 349 x 133 = 385694634780
Therefore, the lowest common multiple of 689,804,180,349,133 is 385694634780.
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.
689 x 804 x 180 x 349 x 133 = 4628335617360
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.
689 : 1, 13, 53, 689
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
349 : 1, 349
133 : 1, 7, 19, 133
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,804,180,349,133, is 1.
Now, the common factors can be found like this.
689:13x 53
804:2x 2x 3x 67
180:2x 2x 3x 3x 5
349:349
133:7x 19
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 3 = 12
Therefore, the value for common factors is 12.
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 = 4628335617360/(1x12)
LCM = 4628335617360/12
LCM = 385694634780
Thus, we can understand that the LCM of 689,804,180,349,133 is 385694634780.
