Given numbers are 362,409,285,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 362,409,285,905 is 42196530.
Find LCM of 362,409,285,905 with Prime Factorization
| 5 | 362, 409, 285, 905 |
| 181 | 362, 409, 57, 181 |
| 2, 409, 57, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 181 x 2 x 409 x 57 x 1 = 42196530
Therefore, the lowest common multiple of 362,409,285,905 is 42196530.
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.
362 x 409 x 285 x 905 = 38187859650
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.
362 : 1, 2, 181, 362
409 : 1, 409
285 : 1, 3, 5, 15, 19, 57, 95, 285
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 362,409,285,905, is 1.
Now, the common factors can be found like this.
362:2x 181
409:409
285:3x 5x 19
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 181 = 905
Therefore, the value for common factors is 905.
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 = 38187859650/(1x905)
LCM = 38187859650/905
LCM = 42196530
Thus, we can understand that the LCM of 362,409,285,905 is 42196530.
