Given numbers are 400,523,692,865
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,523,692,865 is 36191600.
Find LCM of 400,523,692,865 with Prime Factorization
| 2 | 400, 523, 692, 865 |
| 2 | 200, 523, 346, 865 |
| 5 | 100, 523, 173, 865 |
| 173 | 20, 523, 173, 173 |
| 20, 523, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 173 x 20 x 523 x 1 x 1 = 36191600
Therefore, the lowest common multiple of 400,523,692,865 is 36191600.
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.
400 x 523 x 692 x 865 = 125222936000
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
523 : 1, 523
692 : 1, 2, 4, 173, 346, 692
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,523,692,865, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
523:523
692:2x 2x 173
865:5x 173
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 5x 173 = 3460
Therefore, the value for common factors is 3460.
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 = 125222936000/(1x3460)
LCM = 125222936000/3460
LCM = 36191600
Thus, we can understand that the LCM of 400,523,692,865 is 36191600.
