Given numbers are 155,815,748,289
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,815,748,289 is 321269740.
Find LCM of 155,815,748,289 with Prime Factorization
5 | 155, 815, 748, 289 |
17 | 31, 163, 748, 289 |
31, 163, 44, 17 |
Multiply the prime numbers at the bottom and the left side.
5 x 17 x 31 x 163 x 44 x 17 = 321269740
Therefore, the lowest common multiple of 155,815,748,289 is 321269740.
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.
155 x 815 x 748 x 289 = 27307927900
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.
155 : 1, 5, 31, 155
815 : 1, 5, 163, 815
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,815,748,289, is 1.
Now, the common factors can be found like this.
155:5x 31
815:5x 163
748:2x 2x 11x 17
289:17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 17 = 85
Therefore, the value for common factors is 85.
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 = 27307927900/(1x85)
LCM = 27307927900/85
LCM = 321269740
Thus, we can understand that the LCM of 155,815,748,289 is 321269740.
