Given numbers are 378,393,551,128,310
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 378,393,551,128,310 is 270661426560.
Find LCM of 378,393,551,128,310 with Prime Factorization
| 2 | 378, 393, 551, 128, 310 |
| 3 | 189, 393, 551, 64, 155 |
| 63, 131, 551, 64, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 63 x 131 x 551 x 64 x 155 = 270661426560
Therefore, the lowest common multiple of 378,393,551,128,310 is 270661426560.
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.
378 x 393 x 551 x 128 x 310 = 3247937118720
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
393 : 1, 3, 131, 393
551 : 1, 19, 29, 551
128 : 1, 2, 4, 8, 16, 32, 64, 128
310 : 1, 2, 5, 10, 31, 62, 155, 310
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,393,551,128,310, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
393:3x 131
551:19x 29
128:2x 2x 2x 2x 2x 2x 2
310:2x 5x 31
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 3 = 12
Therefore, the value for common factors is 12.
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 = 3247937118720/(1x12)
LCM = 3247937118720/12
LCM = 270661426560
Thus, we can understand that the LCM of 378,393,551,128,310 is 270661426560.
