Given numbers are 608,309,659,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 608,309,659,646 is 2104730016.
Find LCM of 608,309,659,646 with Prime Factorization
| 2 | 608, 309, 659, 646 |
| 19 | 304, 309, 659, 323 |
| 16, 309, 659, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 16 x 309 x 659 x 17 = 2104730016
Therefore, the lowest common multiple of 608,309,659,646 is 2104730016.
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.
608 x 309 x 659 x 646 = 79979740608
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.
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
309 : 1, 3, 103, 309
659 : 1, 659
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 608,309,659,646, is 1.
Now, the common factors can be found like this.
608:2x 2x 2x 2x 2x 19
309:3x 103
659:659
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 79979740608/(1x38)
LCM = 79979740608/38
LCM = 2104730016
Thus, we can understand that the LCM of 608,309,659,646 is 2104730016.
