Given numbers are 404,538,579,402,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 404,538,579,402,642 is 451097883276.
Find LCM of 404,538,579,402,642 with Prime Factorization
2 | 404, 538, 579, 402, 642 |
3 | 202, 269, 579, 201, 321 |
202, 269, 193, 67, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 202 x 269 x 193 x 67 x 107 = 451097883276
Therefore, the lowest common multiple of 404,538,579,402,642 is 451097883276.
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.
404 x 538 x 579 x 402 x 642 = 32479047595872
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.
404 : 1, 2, 4, 101, 202, 404
538 : 1, 2, 269, 538
579 : 1, 3, 193, 579
402 : 1, 2, 3, 6, 67, 134, 201, 402
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 404,538,579,402,642, is 1.
Now, the common factors can be found like this.
404:2x 2x 101
538:2x 269
579:3x 193
402:2x 3x 67
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 32479047595872/(1x72)
LCM = 32479047595872/72
LCM = 451097883276
Thus, we can understand that the LCM of 404,538,579,402,642 is 451097883276.
