Given numbers are 406,251,609,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 406,251,609,986 is 5197206.
Find LCM of 406,251,609,986 with Prime Factorization
| 2 | 406, 251, 609, 986 |
| 7 | 203, 251, 609, 493 |
| 29 | 29, 251, 87, 493 |
| 1, 251, 3, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 29 x 1 x 251 x 3 x 17 = 5197206
Therefore, the lowest common multiple of 406,251,609,986 is 5197206.
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.
406 x 251 x 609 x 986 = 61191903444
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.
406 : 1, 2, 7, 14, 29, 58, 203, 406
251 : 1, 251
609 : 1, 3, 7, 21, 29, 87, 203, 609
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,251,609,986, is 1.
Now, the common factors can be found like this.
406:2x 7x 29
251:251
609:3x 7x 29
986:2x 17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 29x 29 = 11774
Therefore, the value for common factors is 11774.
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 = 61191903444/(1x11774)
LCM = 61191903444/11774
LCM = 5197206
Thus, we can understand that the LCM of 406,251,609,986 is 5197206.
