Given numbers are 960,389,905,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 960,389,905,403 is 27239833920.
Find LCM of 960,389,905,403 with Prime Factorization
| 5 | 960, 389, 905, 403 |
| 192, 389, 181, 403 |
Multiply the prime numbers at the bottom and the left side.
5 x 192 x 389 x 181 x 403 = 27239833920
Therefore, the lowest common multiple of 960,389,905,403 is 27239833920.
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.
960 x 389 x 905 x 403 = 136199169600
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.
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
389 : 1, 389
905 : 1, 5, 181, 905
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 960,389,905,403, is 1.
Now, the common factors can be found like this.
960:2x 2x 2x 2x 2x 2x 3x 5
389:389
905:5x 181
403:13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 136199169600/(1x5)
LCM = 136199169600/5
LCM = 27239833920
Thus, we can understand that the LCM of 960,389,905,403 is 27239833920.
