Given numbers are 689,622,668,525
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,622,668,525 is 75147645300.
Find LCM of 689,622,668,525 with Prime Factorization
| 2 | 689, 622, 668, 525 |
| 689, 311, 334, 525 |
Multiply the prime numbers at the bottom and the left side.
2 x 689 x 311 x 334 x 525 = 75147645300
Therefore, the lowest common multiple of 689,622,668,525 is 75147645300.
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 622 x 668 x 525 = 150295290600
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
622 : 1, 2, 311, 622
668 : 1, 2, 4, 167, 334, 668
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,622,668,525, is 1.
Now, the common factors can be found like this.
689:13x 53
622:2x 311
668:2x 2x 167
525:3x 5x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 150295290600/(1x2)
LCM = 150295290600/2
LCM = 75147645300
Thus, we can understand that the LCM of 689,622,668,525 is 75147645300.
