Find LCM of 442,378,672,838,289 with Prime Factorization
2 | 442, 378, 672, 838, 289 |
3 | 221, 189, 336, 419, 289 |
7 | 221, 63, 112, 419, 289 |
17 | 221, 9, 16, 419, 289 |
13, 9, 16, 419, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 13 x 9 x 16 x 419 x 17 = 9520658784
Therefore, the lowest common multiple of 442,378,672,838,289 is 9520658784.
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.
442 x 378 x 672 x 838 x 289 = 27191001487104
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
838 : 1, 2, 419, 838
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,378,672,838,289, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
378:2x 3x 3x 3x 7
672:2x 2x 2x 2x 2x 3x 7
838:2x 419
289:17x 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 3x 7x 17 = 2856
Therefore, the value for common factors is 2856.
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 = 27191001487104/(1x2856)
LCM = 27191001487104/2856
LCM = 9520658784
Thus, we can understand that the LCM of 442,378,672,838,289 is 9520658784.
