Find LCM of 280,313,416,646,663 with Prime Factorization
| 2 | 280, 313, 416, 646, 663 |
| 2 | 140, 313, 208, 323, 663 |
| 2 | 70, 313, 104, 323, 663 |
| 13 | 35, 313, 52, 323, 663 |
| 17 | 35, 313, 4, 323, 51 |
| 35, 313, 4, 19, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 17 x 35 x 313 x 4 x 19 x 3 = 4416004320
Therefore, the lowest common multiple of 280,313,416,646,663 is 4416004320.
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.
280 x 313 x 416 x 646 x 663 = 15614991275520
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
313 : 1, 313
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
646 : 1, 2, 17, 19, 34, 38, 323, 646
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,313,416,646,663, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
313:313
416:2x 2x 2x 2x 2x 13
646:2x 17x 19
663:3x 13x 17
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 13x 17 = 3536
Therefore, the value for common factors is 3536.
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 = 15614991275520/(1x3536)
LCM = 15614991275520/3536
LCM = 4416004320
Thus, we can understand that the LCM of 280,313,416,646,663 is 4416004320.
