Given numbers are 635,423,381,485
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 635,423,381,485 is 26054685.
Find LCM of 635,423,381,485 with Prime Factorization
| 3 | 635, 423, 381, 485 |
| 5 | 635, 141, 127, 485 |
| 127 | 127, 141, 127, 97 |
| 1, 141, 1, 97 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 127 x 1 x 141 x 1 x 97 = 26054685
Therefore, the lowest common multiple of 635,423,381,485 is 26054685.
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.
635 x 423 x 381 x 485 = 49634174925
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.
635 : 1, 5, 127, 635
423 : 1, 3, 9, 47, 141, 423
381 : 1, 3, 127, 381
485 : 1, 5, 97, 485
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,423,381,485, is 1.
Now, the common factors can be found like this.
635:5x 127
423:3x 3x 47
381:3x 127
485:5x 97
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 127 = 1905
Therefore, the value for common factors is 1905.
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 = 49634174925/(1x1905)
LCM = 49634174925/1905
LCM = 26054685
Thus, we can understand that the LCM of 635,423,381,485 is 26054685.
