Given numbers are 808,145,688,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,145,688,609 is 211590960.
Find LCM of 808,145,688,609 with Prime Factorization
2 | 808, 145, 688, 609 |
2 | 404, 145, 344, 609 |
2 | 202, 145, 172, 609 |
29 | 101, 145, 86, 609 |
101, 5, 86, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 29 x 101 x 5 x 86 x 21 = 211590960
Therefore, the lowest common multiple of 808,145,688,609 is 211590960.
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.
808 x 145 x 688 x 609 = 49089102720
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
145 : 1, 5, 29, 145
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,145,688,609, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
145:5x 29
688:2x 2x 2x 2x 43
609:3x 7x 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 2x 2x 29 = 232
Therefore, the value for common factors is 232.
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 = 49089102720/(1x232)
LCM = 49089102720/232
LCM = 211590960
Thus, we can understand that the LCM of 808,145,688,609 is 211590960.
