Given numbers are 389,520,845,242,554
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,520,845,242,554 is 88137643880.
Find LCM of 389,520,845,242,554 with Prime Factorization
| 2 | 389, 520, 845, 242, 554 |
| 5 | 389, 260, 845, 121, 277 |
| 13 | 389, 52, 169, 121, 277 |
| 389, 4, 13, 121, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 389 x 4 x 13 x 121 x 277 = 88137643880
Therefore, the lowest common multiple of 389,520,845,242,554 is 88137643880.
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 520 x 845 x 242 x 554 = 22915787408800
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
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
845 : 1, 5, 13, 65, 169, 845
242 : 1, 2, 11, 22, 121, 242
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,520,845,242,554, is 1.
Now, the common factors can be found like this.
389:389
520:2x 2x 2x 5x 13
845:5x 13x 13
242:2x 11x 11
554:2x 277
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 22915787408800/(1x260)
LCM = 22915787408800/260
LCM = 88137643880
Thus, we can understand that the LCM of 389,520,845,242,554 is 88137643880.
