Given numbers are 866,338,451,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 866,338,451,221 is 1122096118.
Find LCM of 866,338,451,221 with Prime Factorization
| 2 | 866, 338, 451, 221 |
| 13 | 433, 169, 451, 221 |
| 433, 13, 451, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 433 x 13 x 451 x 17 = 1122096118
Therefore, the lowest common multiple of 866,338,451,221 is 1122096118.
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.
866 x 338 x 451 x 221 = 29174499068
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.
866 : 1, 2, 433, 866
338 : 1, 2, 13, 26, 169, 338
451 : 1, 11, 41, 451
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,338,451,221, is 1.
Now, the common factors can be found like this.
866:2x 433
338:2x 13x 13
451:11x 41
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 29174499068/(1x26)
LCM = 29174499068/26
LCM = 1122096118
Thus, we can understand that the LCM of 866,338,451,221 is 1122096118.
