The LCM of 221,216,292,216 is 3484728.
Find LCM of 221,216,292,216 with Prime Factorization
| 2 | 221, 216, 292, 216 |
| 2 | 221, 108, 146, 108 |
| 2 | 221, 54, 73, 54 |
| 3 | 221, 27, 73, 27 |
| 3 | 221, 9, 73, 9 |
| 3 | 221, 3, 73, 3 |
| 221, 1, 73, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 221 x 1 x 73 x 1 = 3484728
Therefore, the lowest common multiple of 221,216,292,216 is 3484728.
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.
221 x 216 x 292 x 216 = 3010804992
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.
221 : 1, 13, 17, 221
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
292 : 1, 2, 4, 73, 146, 292
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,216,292,216, is 1.
Now, the common factors can be found like this.
221:13x 17
216:2x 2x 2x 3x 3x 3
292:2x 2x 73
216:2x 2x 2x 3x 3x 3
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 3x 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 3010804992/(1x864)
LCM = 3010804992/864
LCM = 3484728
Thus, we can understand that the LCM of 221,216,292,216 is 3484728.
