Find LCM of 672,133,646,348 with Prime Factorization
| 2 | 672, 133, 646, 348 |
| 2 | 336, 133, 323, 174 |
| 3 | 168, 133, 323, 87 |
| 7 | 56, 133, 323, 29 |
| 19 | 8, 19, 323, 29 |
| 8, 1, 17, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 19 x 8 x 1 x 17 x 29 = 6294624
Therefore, the lowest common multiple of 672,133,646,348 is 6294624.
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 133 x 646 x 348 = 20092439808
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
133 : 1, 7, 19, 133
646 : 1, 2, 17, 19, 34, 38, 323, 646
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,133,646,348, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
133:7x 19
646:2x 17x 19
348:2x 2x 3x 29
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 19 = 3192
Therefore, the value for common factors is 3192.
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 = 20092439808/(1x3192)
LCM = 20092439808/3192
LCM = 6294624
Thus, we can understand that the LCM of 672,133,646,348 is 6294624.
