Given numbers are 209,370,657,946,560
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,370,657,946,560 is 122340390480.
Find LCM of 209,370,657,946,560 with Prime Factorization
| 2 | 209, 370, 657, 946, 560 |
| 5 | 209, 185, 657, 473, 280 |
| 11 | 209, 37, 657, 473, 56 |
| 19, 37, 657, 43, 56 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 19 x 37 x 657 x 43 x 56 = 122340390480
Therefore, the lowest common multiple of 209,370,657,946,560 is 122340390480.
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 370 x 657 x 946 x 560 = 26914885905600
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
370 : 1, 2, 5, 10, 37, 74, 185, 370
657 : 1, 3, 9, 73, 219, 657
946 : 1, 2, 11, 22, 43, 86, 473, 946
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,370,657,946,560, is 1.
Now, the common factors can be found like this.
209:11x 19
370:2x 5x 37
657:3x 3x 73
946:2x 11x 43
560:2x 2x 2x 2x 5x 7
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 26914885905600/(1x220)
LCM = 26914885905600/220
LCM = 122340390480
Thus, we can understand that the LCM of 209,370,657,946,560 is 122340390480.
