Given numbers are 429,341,320,645,407
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 429,341,320,645,407 is 6770786880.
Find LCM of 429,341,320,645,407 with Prime Factorization
| 3 | 429, 341, 320, 645, 407 |
| 5 | 143, 341, 320, 215, 407 |
| 11 | 143, 341, 64, 43, 407 |
| 13, 31, 64, 43, 37 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 13 x 31 x 64 x 43 x 37 = 6770786880
Therefore, the lowest common multiple of 429,341,320,645,407 is 6770786880.
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.
429 x 341 x 320 x 645 x 407 = 12288978187200
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.
429 : 1, 3, 11, 13, 33, 39, 143, 429
341 : 1, 11, 31, 341
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
645 : 1, 3, 5, 15, 43, 129, 215, 645
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,341,320,645,407, is 1.
Now, the common factors can be found like this.
429:3x 11x 13
341:11x 31
320:2x 2x 2x 2x 2x 2x 5
645:3x 5x 43
407:11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11x 11 = 1815
Therefore, the value for common factors is 1815.
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 = 12288978187200/(1x1815)
LCM = 12288978187200/1815
LCM = 6770786880
Thus, we can understand that the LCM of 429,341,320,645,407 is 6770786880.
