Given numbers are 689,159,691,153,612
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,159,691,153,612 is 291372588.
Find LCM of 689,159,691,153,612 with Prime Factorization
| 3 | 689, 159, 691, 153, 612 |
| 3 | 689, 53, 691, 51, 204 |
| 17 | 689, 53, 691, 17, 68 |
| 53 | 689, 53, 691, 1, 4 |
| 13, 1, 691, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 53 x 13 x 1 x 691 x 1 x 4 = 291372588
Therefore, the lowest common multiple of 689,159,691,153,612 is 291372588.
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 159 x 691 x 153 x 612 = 7088220948276
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
159 : 1, 3, 53, 159
691 : 1, 691
153 : 1, 3, 9, 17, 51, 153
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,159,691,153,612, is 1.
Now, the common factors can be found like this.
689:13x 53
159:3x 53
691:691
153:3x 3x 17
612:2x 2x 3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 17x 53 = 24327
Therefore, the value for common factors is 24327.
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 = 7088220948276/(1x24327)
LCM = 7088220948276/24327
LCM = 291372588
Thus, we can understand that the LCM of 689,159,691,153,612 is 291372588.
