Find LCM of 646,546,663,163 with Prime Factorization
| 2 | 646, 546, 663, 163 |
| 3 | 323, 273, 663, 163 |
| 13 | 323, 91, 221, 163 |
| 17 | 323, 7, 17, 163 |
| 19, 7, 1, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 19 x 7 x 1 x 163 = 28746354
Therefore, the lowest common multiple of 646,546,663,163 is 28746354.
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.
646 x 546 x 663 x 163 = 38117665404
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
663 : 1, 3, 13, 17, 39, 51, 221, 663
163 : 1, 163
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,546,663,163, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
546:2x 3x 7x 13
663:3x 13x 17
163:163
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 13x 17 = 1326
Therefore, the value for common factors is 1326.
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 = 38117665404/(1x1326)
LCM = 38117665404/1326
LCM = 28746354
Thus, we can understand that the LCM of 646,546,663,163 is 28746354.
