Given numbers are 605,105,574,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,105,574,842 is 438602010.
Find LCM of 605,105,574,842 with Prime Factorization
2 | 605, 105, 574, 842 |
5 | 605, 105, 287, 421 |
7 | 121, 21, 287, 421 |
121, 3, 41, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 121 x 3 x 41 x 421 = 438602010
Therefore, the lowest common multiple of 605,105,574,842 is 438602010.
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.
605 x 105 x 574 x 842 = 30702140700
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.
605 : 1, 5, 11, 55, 121, 605
105 : 1, 3, 5, 7, 15, 21, 35, 105
574 : 1, 2, 7, 14, 41, 82, 287, 574
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,105,574,842, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
105:3x 5x 7
574:2x 7x 41
842:2x 421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7 = 70
Therefore, the value for common factors is 70.
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 = 30702140700/(1x70)
LCM = 30702140700/70
LCM = 438602010
Thus, we can understand that the LCM of 605,105,574,842 is 438602010.
