Find LCM of 945,857,624,224 with Prime Factorization
| 2 | 945, 857, 624, 224 |
| 2 | 945, 857, 312, 112 |
| 2 | 945, 857, 156, 56 |
| 2 | 945, 857, 78, 28 |
| 3 | 945, 857, 39, 14 |
| 7 | 315, 857, 13, 14 |
| 45, 857, 13, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 45 x 857 x 13 x 2 = 336903840
Therefore, the lowest common multiple of 945,857,624,224 is 336903840.
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.
945 x 857 x 624 x 224 = 113199690240
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
857 : 1, 857
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,857,624,224, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
857:857
624:2x 2x 2x 2x 3x 13
224:2x 2x 2x 2x 2x 7
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 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 113199690240/(1x336)
LCM = 113199690240/336
LCM = 336903840
Thus, we can understand that the LCM of 945,857,624,224 is 336903840.
