Given numbers are 209,573,855,470
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,573,855,470 is 168857370.
Find LCM of 209,573,855,470 with Prime Factorization
| 3 | 209, 573, 855, 470 |
| 5 | 209, 191, 285, 470 |
| 19 | 209, 191, 57, 94 |
| 11, 191, 3, 94 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 11 x 191 x 3 x 94 = 168857370
Therefore, the lowest common multiple of 209,573,855,470 is 168857370.
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.
209 x 573 x 855 x 470 = 48124350450
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.
209 : 1, 11, 19, 209
573 : 1, 3, 191, 573
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
470 : 1, 2, 5, 10, 47, 94, 235, 470
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,573,855,470, is 1.
Now, the common factors can be found like this.
209:11x 19
573:3x 191
855:3x 3x 5x 19
470:2x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 19 = 285
Therefore, the value for common factors is 285.
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 = 48124350450/(1x285)
LCM = 48124350450/285
LCM = 168857370
Thus, we can understand that the LCM of 209,573,855,470 is 168857370.
