Given numbers are 591,390,595,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 591,390,595,689 is 484566810.
Find LCM of 591,390,595,689 with Prime Factorization
| 3 | 591, 390, 595, 689 |
| 5 | 197, 130, 595, 689 |
| 13 | 197, 26, 119, 689 |
| 197, 2, 119, 53 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 197 x 2 x 119 x 53 = 484566810
Therefore, the lowest common multiple of 591,390,595,689 is 484566810.
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.
591 x 390 x 595 x 689 = 94490527950
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.
591 : 1, 3, 197, 591
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
595 : 1, 5, 7, 17, 35, 85, 119, 595
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 591,390,595,689, is 1.
Now, the common factors can be found like this.
591:3x 197
390:2x 3x 5x 13
595:5x 7x 17
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13 = 195
Therefore, the value for common factors is 195.
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 = 94490527950/(1x195)
LCM = 94490527950/195
LCM = 484566810
Thus, we can understand that the LCM of 591,390,595,689 is 484566810.
