Find LCM of 400,392,352,350,257 with Prime Factorization
| 2 | 400, 392, 352, 350, 257 |
| 2 | 200, 196, 176, 175, 257 |
| 2 | 100, 98, 88, 175, 257 |
| 2 | 50, 49, 44, 175, 257 |
| 5 | 25, 49, 22, 175, 257 |

| 7 | 1, 49, 22, 7, 257 |
| 1, 1, 22, 7, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 5 x 7 x 1 x 1 x 22 x 7 x 257 = 110818400
Therefore, the lowest common multiple of 400,392,352,350,257 is 110818400.
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 392 x 352 x 350 x 257 = 4964664320000
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
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,392,352,350,257, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
392:2x 2x 2x 7x 7
352:2x 2x 2x 2x 2x 11
350:2x 5x 5x 7
257:257
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 2x 5x 5x 7 = 44800
Therefore, the value for common factors is 44800.
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 = 4964664320000/(1x44800)
LCM = 4964664320000/44800
LCM = 110818400
Thus, we can understand that the LCM of 400,392,352,350,257 is 110818400.
