Find LCM of 400,385,668,578,832 with Prime Factorization
| 2 | 400, 385, 668, 578, 832 |
| 2 | 200, 385, 334, 289, 416 |
| 2 | 100, 385, 167, 289, 208 |
| 2 | 50, 385, 167, 289, 104 |
| 5 | 25, 385, 167, 289, 52 |
| 5, 77, 167, 289, 52 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 5 x 77 x 167 x 289 x 52 = 77298020800
Therefore, the lowest common multiple of 400,385,668,578,832 is 77298020800.
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.
400 x 385 x 668 x 578 x 832 = 49470733312000
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
385 : 1, 5, 7, 11, 35, 55, 77, 385
668 : 1, 2, 4, 167, 334, 668
578 : 1, 2, 17, 34, 289, 578
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,385,668,578,832, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
385:5x 7x 11
668:2x 2x 167
578:2x 17x 17
832:2x 2x 2x 2x 2x 2x 13
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 5 = 640
Therefore, the value for common factors is 640.
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 = 49470733312000/(1x640)
LCM = 49470733312000/640
LCM = 77298020800
Thus, we can understand that the LCM of 400,385,668,578,832 is 77298020800.
