Find LCM of 672,400,975,664 with Prime Factorization
| 2 | 672, 400, 975, 664 |
| 2 | 336, 200, 975, 332 |
| 2 | 168, 100, 975, 166 |
| 2 | 84, 50, 975, 83 |
| 3 | 42, 25, 975, 83 |
| 5 | 14, 25, 325, 83 |
| 5 | 14, 5, 65, 83 |
| 14, 1, 13, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 5 x 14 x 1 x 13 x 83 = 18127200
Therefore, the lowest common multiple of 672,400,975,664 is 18127200.
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 400 x 975 x 664 = 174021120000
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
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,400,975,664, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
400:2x 2x 2x 2x 5x 5
975:3x 5x 5x 13
664:2x 2x 2x 83
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 2x 3x 5x 5 = 9600
Therefore, the value for common factors is 9600.
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 = 174021120000/(1x9600)
LCM = 174021120000/9600
LCM = 18127200
Thus, we can understand that the LCM of 672,400,975,664 is 18127200.
