Given numbers are 678,343,681,924
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,343,681,924 is 1161374676.
Find LCM of 678,343,681,924 with Prime Factorization
| 2 | 678, 343, 681, 924 |
| 3 | 339, 343, 681, 462 |
| 7 | 113, 343, 227, 154 |
| 113, 49, 227, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 113 x 49 x 227 x 22 = 1161374676
Therefore, the lowest common multiple of 678,343,681,924 is 1161374676.
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.
678 x 343 x 681 x 924 = 146333209176
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
343 : 1, 7, 49, 343
681 : 1, 3, 227, 681
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,343,681,924, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
343:7x 7x 7
681:3x 227
924:2x 2x 3x 7x 11
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 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 146333209176/(1x126)
LCM = 146333209176/126
LCM = 1161374676
Thus, we can understand that the LCM of 678,343,681,924 is 1161374676.
