Find LCM of 378,124,356,486,666 with Prime Factorization
| 2 | 378, 124, 356, 486, 666 |
| 2 | 189, 62, 178, 243, 333 |
| 3 | 189, 31, 89, 243, 333 |
| 3 | 63, 31, 89, 81, 111 |
| 3 | 21, 31, 89, 27, 37 |
| 7, 31, 89, 9, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 7 x 31 x 89 x 9 x 37 = 694572732
Therefore, the lowest common multiple of 378,124,356,486,666 is 694572732.
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 124 x 356 x 486 x 666 = 5400997564032
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
124 : 1, 2, 4, 31, 62, 124
356 : 1, 2, 4, 89, 178, 356
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,124,356,486,666, is 2.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
124:2x 2x 31
356:2x 2x 89
486:2x 3x 3x 3x 3x 3
666:2x 3x 3x 37
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 3x 3x 3 = 3888
Therefore, the value for common factors is 3888.
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 = 5400997564032/(2x3888)
LCM = 5400997564032/7776
LCM = 694572732
Thus, we can understand that the LCM of 378,124,356,486,666 is 694572732.
