Given numbers are 144,551,634,174,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 144,551,634,174,689 is 17329761072.
Find LCM of 144,551,634,174,689 with Prime Factorization
| 2 | 144, 551, 634, 174, 689 |
| 3 | 72, 551, 317, 87, 689 |
| 29 | 24, 551, 317, 29, 689 |
| 24, 19, 317, 1, 689 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 24 x 19 x 317 x 1 x 689 = 17329761072
Therefore, the lowest common multiple of 144,551,634,174,689 is 17329761072.
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.
144 x 551 x 634 x 174 x 689 = 6030756853056
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.
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
551 : 1, 19, 29, 551
634 : 1, 2, 317, 634
174 : 1, 2, 3, 6, 29, 58, 87, 174
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,551,634,174,689, is 1.
Now, the common factors can be found like this.
144:2x 2x 2x 2x 3x 3
551:19x 29
634:2x 317
174:2x 3x 29
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.
2x 2x 3x 29 = 348
Therefore, the value for common factors is 348.
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 = 6030756853056/(1x348)
LCM = 6030756853056/348
LCM = 17329761072
Thus, we can understand that the LCM of 144,551,634,174,689 is 17329761072.
