Given numbers are 805,407,627,249
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,407,627,249 is 1550041185.
Find LCM of 805,407,627,249 with Prime Factorization
| 3 | 805, 407, 627, 249 |
| 11 | 805, 407, 209, 83 |
| 805, 37, 19, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 805 x 37 x 19 x 83 = 1550041185
Therefore, the lowest common multiple of 805,407,627,249 is 1550041185.
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.
805 x 407 x 627 x 249 = 51151359105
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
407 : 1, 11, 37, 407
627 : 1, 3, 11, 19, 33, 57, 209, 627
249 : 1, 3, 83, 249
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,407,627,249, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
407:11x 37
627:3x 11x 19
249:3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 51151359105/(1x33)
LCM = 51151359105/33
LCM = 1550041185
Thus, we can understand that the LCM of 805,407,627,249 is 1550041185.
