Given numbers are 689,858,286,274
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,858,286,274 is 6229938.
Find LCM of 689,858,286,274 with Prime Factorization
| 2 | 689, 858, 286, 274 |
| 11 | 689, 429, 143, 137 |
| 13 | 689, 39, 13, 137 |
| 53, 3, 1, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 53 x 3 x 1 x 137 = 6229938
Therefore, the lowest common multiple of 689,858,286,274 is 6229938.
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.
689 x 858 x 286 x 274 = 46325818968
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.
689 : 1, 13, 53, 689
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
286 : 1, 2, 11, 13, 22, 26, 143, 286
274 : 1, 2, 137, 274
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,858,286,274, is 1.
Now, the common factors can be found like this.
689:13x 53
858:2x 3x 11x 13
286:2x 11x 13
274:2x 137
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 11x 13x 13 = 7436
Therefore, the value for common factors is 7436.
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 = 46325818968/(1x7436)
LCM = 46325818968/7436
LCM = 6229938
Thus, we can understand that the LCM of 689,858,286,274 is 6229938.
