Find LCM of 912,221,224,663 with Prime Factorization
| 2 | 912, 221, 224, 663 |
| 2 | 456, 221, 112, 663 |
| 2 | 228, 221, 56, 663 |
| 2 | 114, 221, 28, 663 |
| 3 | 57, 221, 14, 663 |
| 13 | 19, 221, 14, 221 |
| 17 | 19, 17, 14, 17 |
| 19, 1, 14, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 13 x 17 x 19 x 1 x 14 x 1 = 2821728
Therefore, the lowest common multiple of 912,221,224,663 is 2821728.
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.
912 x 221 x 224 x 663 = 29932890624
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
221 : 1, 13, 17, 221
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,221,224,663, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
221:13x 17
224:2x 2x 2x 2x 2x 7
663:3x 13x 17
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 13x 17 = 10608
Therefore, the value for common factors is 10608.
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 = 29932890624/(1x10608)
LCM = 29932890624/10608
LCM = 2821728
Thus, we can understand that the LCM of 912,221,224,663 is 2821728.
