Given numbers are 663,740,686,402,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 663,740,686,402,494 is 214223826180.
Find LCM of 663,740,686,402,494 with Prime Factorization
| 2 | 663, 740, 686, 402, 494 |
| 3 | 663, 370, 343, 201, 247 |
| 13 | 221, 370, 343, 67, 247 |
| 17, 370, 343, 67, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 370 x 343 x 67 x 19 = 214223826180
Therefore, the lowest common multiple of 663,740,686,402,494 is 214223826180.
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.
663 x 740 x 686 x 402 x 494 = 66837833768160
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.
663 : 1, 3, 13, 17, 39, 51, 221, 663
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
686 : 1, 2, 7, 14, 49, 98, 343, 686
402 : 1, 2, 3, 6, 67, 134, 201, 402
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,740,686,402,494, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
740:2x 2x 5x 37
686:2x 7x 7x 7
402:2x 3x 67
494:2x 13x 19
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 3x 13 = 312
Therefore, the value for common factors is 312.
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 = 66837833768160/(1x312)
LCM = 66837833768160/312
LCM = 214223826180
Thus, we can understand that the LCM of 663,740,686,402,494 is 214223826180.
