Find LCM of 672,589,434,656,798 with Prime Factorization
| 2 | 672, 589, 434, 656, 798 |
| 2 | 336, 589, 217, 328, 399 |
| 2 | 168, 589, 217, 164, 399 |
| 2 | 84, 589, 217, 82, 399 |
| 3 | 42, 589, 217, 41, 399 |
| 7 | 14, 589, 217, 41, 133 |
| 19 | 2, 589, 31, 41, 19 |
| 31 | 2, 31, 31, 41, 1 |
| 2, 1, 1, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 19 x 31 x 2 x 1 x 1 x 41 x 1 = 16228128
Therefore, the lowest common multiple of 672,589,434,656,798 is 16228128.
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.
672 x 589 x 434 x 656 x 798 = 89925120423936
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.
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
589 : 1, 19, 31, 589
434 : 1, 2, 7, 14, 31, 62, 217, 434
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,589,434,656,798, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
589:19x 31
434:2x 7x 31
656:2x 2x 2x 2x 41
798:2x 3x 7x 19
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 2x 2x 3x 7x 7x 19x 31 = 5541312
Therefore, the value for common factors is 5541312.
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 = 89925120423936/(1x5541312)
LCM = 89925120423936/5541312
LCM = 16228128
Thus, we can understand that the LCM of 672,589,434,656,798 is 16228128.
