Given numbers are 892,677,120,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 892,677,120,689 is 12482282280.
Find LCM of 892,677,120,689 with Prime Factorization
| 2 | 892, 677, 120, 689 |
| 2 | 446, 677, 60, 689 |
| 223, 677, 30, 689 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 223 x 677 x 30 x 689 = 12482282280
Therefore, the lowest common multiple of 892,677,120,689 is 12482282280.
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.
892 x 677 x 120 x 689 = 49929129120
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.
892 : 1, 2, 4, 223, 446, 892
677 : 1, 677
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 892,677,120,689, is 1.
Now, the common factors can be found like this.
892:2x 2x 223
677:677
120:2x 2x 2x 3x 5
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 49929129120/(1x4)
LCM = 49929129120/4
LCM = 12482282280
Thus, we can understand that the LCM of 892,677,120,689 is 12482282280.
