Given numbers are 380,327,987,228,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,327,987,228,628 is 6418401780.
Find LCM of 380,327,987,228,628 with Prime Factorization
| 2 | 380, 327, 987, 228, 628 |
| 2 | 190, 327, 987, 114, 314 |
| 3 | 95, 327, 987, 57, 157 |
| 19 | 95, 109, 329, 19, 157 |
| 5, 109, 329, 1, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 5 x 109 x 329 x 1 x 157 = 6418401780
Therefore, the lowest common multiple of 380,327,987,228,628 is 6418401780.
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 327 x 987 x 228 x 628 = 17560747270080
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
327 : 1, 3, 109, 327
987 : 1, 3, 7, 21, 47, 141, 329, 987
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,327,987,228,628, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
327:3x 109
987:3x 7x 47
228:2x 2x 3x 19
628:2x 2x 157
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 2x 2x 3x 3x 19 = 2736
Therefore, the value for common factors is 2736.
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 = 17560747270080/(1x2736)
LCM = 17560747270080/2736
LCM = 6418401780
Thus, we can understand that the LCM of 380,327,987,228,628 is 6418401780.
