Given numbers are 389,589,434,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,589,434,403 is 41700022.
Find LCM of 389,589,434,403 with Prime Factorization
| 31 | 389, 589, 434, 403 |
| 389, 19, 14, 13 |
Multiply the prime numbers at the bottom and the left side.
31 x 389 x 19 x 14 x 13 = 41700022
Therefore, the lowest common multiple of 389,589,434,403 is 41700022.
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.
389 x 589 x 434 x 403 = 40073721142
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.
389 : 1, 389
589 : 1, 19, 31, 589
434 : 1, 2, 7, 14, 31, 62, 217, 434
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,589,434,403, is 1.
Now, the common factors can be found like this.
389:389
589:19x 31
434:2x 7x 31
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.
31x 31 = 961
Therefore, the value for common factors is 961.
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 = 40073721142/(1x961)
LCM = 40073721142/961
LCM = 41700022
Thus, we can understand that the LCM of 389,589,434,403 is 41700022.
