Given numbers are 287,286,403,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,286,403,649 is 150127978.
Find LCM of 287,286,403,649 with Prime Factorization
| 11 | 287, 286, 403, 649 |
| 13 | 287, 26, 403, 59 |
| 287, 2, 31, 59 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 287 x 2 x 31 x 59 = 150127978
Therefore, the lowest common multiple of 287,286,403,649 is 150127978.
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.
287 x 286 x 403 x 649 = 21468300854
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.
287 : 1, 7, 41, 287
286 : 1, 2, 11, 13, 22, 26, 143, 286
403 : 1, 13, 31, 403
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,286,403,649, is 1.
Now, the common factors can be found like this.
287:7x 41
286:2x 11x 13
403:13x 31
649:11x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 13 = 143
Therefore, the value for common factors is 143.
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 = 21468300854/(1x143)
LCM = 21468300854/143
LCM = 150127978
Thus, we can understand that the LCM of 287,286,403,649 is 150127978.
