Given numbers are 493,671,209,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 493,671,209,969 is 18855771.
Find LCM of 493,671,209,969 with Prime Factorization
| 11 | 493, 671, 209, 969 |
| 17 | 493, 61, 19, 969 |
| 19 | 29, 61, 19, 57 |
| 29, 61, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 19 x 29 x 61 x 1 x 3 = 18855771
Therefore, the lowest common multiple of 493,671,209,969 is 18855771.
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.
493 x 671 x 209 x 969 = 66994554363
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.
493 : 1, 17, 29, 493
671 : 1, 11, 61, 671
209 : 1, 11, 19, 209
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,671,209,969, is 1.
Now, the common factors can be found like this.
493:17x 29
671:11x 61
209:11x 19
969:3x 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.
11x 17x 19 = 3553
Therefore, the value for common factors is 3553.
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 = 66994554363/(1x3553)
LCM = 66994554363/3553
LCM = 18855771
Thus, we can understand that the LCM of 493,671,209,969 is 18855771.
