Given numbers are 378,281,843,520
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 378,281,843,520 is 27616680.
Find LCM of 378,281,843,520 with Prime Factorization
| 2 | 378, 281, 843, 520 |
| 3 | 189, 281, 843, 260 |
| 281 | 63, 281, 281, 260 |
| 63, 1, 1, 260 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 281 x 63 x 1 x 1 x 260 = 27616680
Therefore, the lowest common multiple of 378,281,843,520 is 27616680.
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 281 x 843 x 520 = 46561722480
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
281 : 1, 281
843 : 1, 3, 281, 843
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,281,843,520, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
281:281
843:3x 281
520:2x 2x 2x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 281 = 1686
Therefore, the value for common factors is 1686.
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 = 46561722480/(1x1686)
LCM = 46561722480/1686
LCM = 27616680
Thus, we can understand that the LCM of 378,281,843,520 is 27616680.
