Given numbers are 824,676,678,869
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 824,676,678,869 is 41023564296.
Find LCM of 824,676,678,869 with Prime Factorization
| 2 | 824, 676, 678, 869 |
| 2 | 412, 338, 339, 869 |
| 206, 169, 339, 869 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 206 x 169 x 339 x 869 = 41023564296
Therefore, the lowest common multiple of 824,676,678,869 is 41023564296.
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.
824 x 676 x 678 x 869 = 328188514368
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.
824 : 1, 2, 4, 8, 103, 206, 412, 824
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
678 : 1, 2, 3, 6, 113, 226, 339, 678
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,676,678,869, is 1.
Now, the common factors can be found like this.
824:2x 2x 2x 103
676:2x 2x 13x 13
678:2x 3x 113
869:11x 79
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 2 = 8
Therefore, the value for common factors is 8.
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 = 328188514368/(1x8)
LCM = 328188514368/8
LCM = 41023564296
Thus, we can understand that the LCM of 824,676,678,869 is 41023564296.
