Given numbers are 403,587,286,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,587,286,638 is 150925918.
Find LCM of 403,587,286,638 with Prime Factorization
2 | 403, 587, 286, 638 |
11 | 403, 587, 143, 319 |
13 | 403, 587, 13, 29 |
31, 587, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 31 x 587 x 1 x 29 = 150925918
Therefore, the lowest common multiple of 403,587,286,638 is 150925918.
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.
403 x 587 x 286 x 638 = 43164812548
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.
403 : 1, 13, 31, 403
587 : 1, 587
286 : 1, 2, 11, 13, 22, 26, 143, 286
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,587,286,638, is 1.
Now, the common factors can be found like this.
403:13x 31
587:587
286:2x 11x 13
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 13 = 286
Therefore, the value for common factors is 286.
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 = 43164812548/(1x286)
LCM = 43164812548/286
LCM = 150925918
Thus, we can understand that the LCM of 403,587,286,638 is 150925918.
