Given numbers are 153,663,987,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 153,663,987,689 is 34682193.
Find LCM of 153,663,987,689 with Prime Factorization
| 3 | 153, 663, 987, 689 |
| 13 | 51, 221, 329, 689 |
| 17 | 51, 17, 329, 53 |
| 3, 1, 329, 53 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 17 x 3 x 1 x 329 x 53 = 34682193
Therefore, the lowest common multiple of 153,663,987,689 is 34682193.
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.
153 x 663 x 987 x 689 = 68982881877
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.
153 : 1, 3, 9, 17, 51, 153
663 : 1, 3, 13, 17, 39, 51, 221, 663
987 : 1, 3, 7, 21, 47, 141, 329, 987
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,663,987,689, is 1.
Now, the common factors can be found like this.
153:3x 3x 17
663:3x 13x 17
987:3x 7x 47
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 3x 13x 17 = 1989
Therefore, the value for common factors is 1989.
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 = 68982881877/(1x1989)
LCM = 68982881877/1989
LCM = 34682193
Thus, we can understand that the LCM of 153,663,987,689 is 34682193.
