Find LCM of 647,176,166,380,800 with Prime Factorization
| 2 | 647, 176, 166, 380, 800 |
| 2 | 647, 88, 83, 190, 400 |
| 2 | 647, 44, 83, 95, 200 |
| 2 | 647, 22, 83, 95, 100 |
| 5 | 647, 11, 83, 95, 50 |
| 647, 11, 83, 19, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 647 x 11 x 83 x 19 x 10 = 8978807200
Therefore, the lowest common multiple of 647,176,166,380,800 is 8978807200.
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.
647 x 176 x 166 x 380 x 800 = 5746436608000
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.
647 : 1, 647
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
166 : 1, 2, 83, 166
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,176,166,380,800, is 1.
Now, the common factors can be found like this.
647:647
176:2x 2x 2x 2x 11
166:2x 83
380:2x 2x 5x 19
800:2x 2x 2x 2x 2x 5x 5
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 = 5746436608000/(1x640)
LCM = 5746436608000/640
LCM = 8978807200
Thus, we can understand that the LCM of 647,176,166,380,800 is 8978807200.
