Given numbers are 671,121,261,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,121,261,494 is 951661854.
Find LCM of 671,121,261,494 with Prime Factorization
| 11 | 671, 121, 261, 494 |
| 61, 11, 261, 494 |
Multiply the prime numbers at the bottom and the left side.
11 x 61 x 11 x 261 x 494 = 951661854
Therefore, the lowest common multiple of 671,121,261,494 is 951661854.
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.
671 x 121 x 261 x 494 = 10468280394
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.
671 : 1, 11, 61, 671
121 : 1, 11, 121
261 : 1, 3, 9, 29, 87, 261
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,121,261,494, is 1.
Now, the common factors can be found like this.
671:11x 61
121:11x 11
261:3x 3x 29
494:2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 10468280394/(1x11)
LCM = 10468280394/11
LCM = 951661854
Thus, we can understand that the LCM of 671,121,261,494 is 951661854.
