Given numbers are 642,802,879,608
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,802,879,608 is 22930873824.
Find LCM of 642,802,879,608 with Prime Factorization
| 2 | 642, 802, 879, 608 |
| 3 | 321, 401, 879, 304 |
| 107, 401, 293, 304 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 401 x 293 x 304 = 22930873824
Therefore, the lowest common multiple of 642,802,879,608 is 22930873824.
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.
642 x 802 x 879 x 608 = 275170485888
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
802 : 1, 2, 401, 802
879 : 1, 3, 293, 879
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,802,879,608, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
802:2x 401
879:3x 293
608:2x 2x 2x 2x 2x 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 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 275170485888/(1x12)
LCM = 275170485888/12
LCM = 22930873824
Thus, we can understand that the LCM of 642,802,879,608 is 22930873824.
