Given numbers are 112,689,905,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 112,689,905,689 is 69837040.
Find LCM of 112,689,905,689 with Prime Factorization
| 13 | 112, 689, 905, 689 |
| 53 | 112, 53, 905, 53 |
| 112, 1, 905, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 53 x 112 x 1 x 905 x 1 = 69837040
Therefore, the lowest common multiple of 112,689,905,689 is 69837040.
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.
112 x 689 x 905 x 689 = 48117720560
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.
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
689 : 1, 13, 53, 689
905 : 1, 5, 181, 905
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 112,689,905,689, is 1.
Now, the common factors can be found like this.
112:2x 2x 2x 2x 7
689:13x 53
905:5x 181
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.
13x 53 = 689
Therefore, the value for common factors is 689.
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 = 48117720560/(1x689)
LCM = 48117720560/689
LCM = 69837040
Thus, we can understand that the LCM of 112,689,905,689 is 69837040.
