Given numbers are 380,184,203,551,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,184,203,551,861 is 436458120.
Find LCM of 380,184,203,551,861 with Prime Factorization
| 2 | 380, 184, 203, 551, 861 |
| 2 | 190, 92, 203, 551, 861 |
| 7 | 95, 46, 203, 551, 861 |
| 19 | 95, 46, 29, 551, 123 |
| 29 | 5, 46, 29, 29, 123 |
| 5, 46, 1, 1, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 29 x 5 x 46 x 1 x 1 x 123 = 436458120
Therefore, the lowest common multiple of 380,184,203,551,861 is 436458120.
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.
380 x 184 x 203 x 551 x 861 = 6733675875360
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
184 : 1, 2, 4, 8, 23, 46, 92, 184
203 : 1, 7, 29, 203
551 : 1, 19, 29, 551
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,184,203,551,861, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
184:2x 2x 2x 23
203:7x 29
551:19x 29
861:3x 7x 41
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 7x 19x 29 = 15428
Therefore, the value for common factors is 15428.
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 = 6733675875360/(1x15428)
LCM = 6733675875360/15428
LCM = 436458120
Thus, we can understand that the LCM of 380,184,203,551,861 is 436458120.
