Given numbers are 905,418,190,412
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,418,190,412 is 77927740.
Find LCM of 905,418,190,412 with Prime Factorization
| 2 | 905, 418, 190, 412 |
| 5 | 905, 209, 95, 206 |
| 19 | 181, 209, 19, 206 |
| 181, 11, 1, 206 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 181 x 11 x 1 x 206 = 77927740
Therefore, the lowest common multiple of 905,418,190,412 is 77927740.
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.
905 x 418 x 190 x 412 = 29612541200
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.
905 : 1, 5, 181, 905
418 : 1, 2, 11, 19, 22, 38, 209, 418
190 : 1, 2, 5, 10, 19, 38, 95, 190
412 : 1, 2, 4, 103, 206, 412
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,418,190,412, is 1.
Now, the common factors can be found like this.
905:5x 181
418:2x 11x 19
190:2x 5x 19
412:2x 2x 103
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 19 = 380
Therefore, the value for common factors is 380.
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 = 29612541200/(1x380)
LCM = 29612541200/380
LCM = 77927740
Thus, we can understand that the LCM of 905,418,190,412 is 77927740.
