Given numbers are 529,418,278,561,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 529,418,278,561,821 is 1286945297418.
Find LCM of 529,418,278,561,821 with Prime Factorization
| 2 | 529, 418, 278, 561, 821 |
| 11 | 529, 209, 139, 561, 821 |
| 529, 19, 139, 51, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 529 x 19 x 139 x 51 x 821 = 1286945297418
Therefore, the lowest common multiple of 529,418,278,561,821 is 1286945297418.
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.
529 x 418 x 278 x 561 x 821 = 28312796543196
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.
529 : 1, 23, 529
418 : 1, 2, 11, 19, 22, 38, 209, 418
278 : 1, 2, 139, 278
561 : 1, 3, 11, 17, 33, 51, 187, 561
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 529,418,278,561,821, is 1.
Now, the common factors can be found like this.
529:23x 23
418:2x 11x 19
278:2x 139
561:3x 11x 17
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 28312796543196/(1x22)
LCM = 28312796543196/22
LCM = 1286945297418
Thus, we can understand that the LCM of 529,418,278,561,821 is 1286945297418.
