Given numbers are 493,523,690,945,245
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 493,523,690,945,245 is 78457829310.
Find LCM of 493,523,690,945,245 with Prime Factorization
| 3 | 493, 523, 690, 945, 245 |
| 5 | 493, 523, 230, 315, 245 |
| 7 | 493, 523, 46, 63, 49 |
| 493, 523, 46, 9, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 493 x 523 x 46 x 9 x 7 = 78457829310
Therefore, the lowest common multiple of 493,523,690,945,245 is 78457829310.
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 523 x 690 x 945 x 245 = 41190360387750
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
523 : 1, 523
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,523,690,945,245, is 1.
Now, the common factors can be found like this.
493:17x 29
523:523
690:2x 3x 5x 23
945:3x 3x 3x 5x 7
245:5x 7x 7
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 5x 7 = 525
Therefore, the value for common factors is 525.
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 = 41190360387750/(1x525)
LCM = 41190360387750/525
LCM = 78457829310
Thus, we can understand that the LCM of 493,523,690,945,245 is 78457829310.
