Given numbers are 842,646,575,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 842,646,575,667 is 4535033050.
Find LCM of 842,646,575,667 with Prime Factorization
| 2 | 842, 646, 575, 667 |
| 23 | 421, 323, 575, 667 |
| 421, 323, 25, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 421 x 323 x 25 x 29 = 4535033050
Therefore, the lowest common multiple of 842,646,575,667 is 4535033050.
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.
842 x 646 x 575 x 667 = 208611520300
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.
842 : 1, 2, 421, 842
646 : 1, 2, 17, 19, 34, 38, 323, 646
575 : 1, 5, 23, 25, 115, 575
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,646,575,667, is 1.
Now, the common factors can be found like this.
842:2x 421
646:2x 17x 19
575:5x 5x 23
667:23x 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 23 = 46
Therefore, the value for common factors is 46.
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 = 208611520300/(1x46)
LCM = 208611520300/46
LCM = 4535033050
Thus, we can understand that the LCM of 842,646,575,667 is 4535033050.
