Find LCM of 345,665,663,910,910 with Prime Factorization
| 2 | 345, 665, 663, 910, 910 |
| 3 | 345, 665, 663, 455, 455 |
| 5 | 115, 665, 221, 455, 455 |
| 7 | 23, 133, 221, 91, 91 |
| 13 | 23, 19, 221, 13, 13 |
| 23, 19, 17, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 13 x 23 x 19 x 17 x 1 x 1 = 20281170
Therefore, the lowest common multiple of 345,665,663,910,910 is 20281170.
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.
345 x 665 x 663 x 910 x 910 = 125961276577500
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
665 : 1, 5, 7, 19, 35, 95, 133, 665
663 : 1, 3, 13, 17, 39, 51, 221, 663
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,665,663,910,910, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
665:5x 7x 19
663:3x 13x 17
910:2x 5x 7x 13
910:2x 5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5x 5x 7x 7x 13x 13 = 6210750
Therefore, the value for common factors is 6210750.
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 = 125961276577500/(1x6210750)
LCM = 125961276577500/6210750
LCM = 20281170
Thus, we can understand that the LCM of 345,665,663,910,910 is 20281170.
