Given numbers are 455,663,760,340,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,663,760,340,788 is 694850520.
Find LCM of 455,663,760,340,788 with Prime Factorization
| 2 | 455, 663, 760, 340, 788 |
| 2 | 455, 663, 380, 170, 394 |
| 5 | 455, 663, 190, 85, 197 |
| 13 | 91, 663, 38, 17, 197 |
| 17 | 7, 51, 38, 17, 197 |
| 7, 3, 38, 1, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 17 x 7 x 3 x 38 x 1 x 197 = 694850520
Therefore, the lowest common multiple of 455,663,760,340,788 is 694850520.
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.
455 x 663 x 760 x 340 x 788 = 61424785968000
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
663 : 1, 3, 13, 17, 39, 51, 221, 663
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,663,760,340,788, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
663:3x 13x 17
760:2x 2x 2x 5x 19
340:2x 2x 5x 17
788:2x 2x 197
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 2x 5x 5x 13x 17 = 88400
Therefore, the value for common factors is 88400.
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 = 61424785968000/(1x88400)
LCM = 61424785968000/88400
LCM = 694850520
Thus, we can understand that the LCM of 455,663,760,340,788 is 694850520.
