Find LCM of 544,210,120,221,238 with Prime Factorization
| 2 | 544, 210, 120, 221, 238 |
| 2 | 272, 105, 60, 221, 119 |
| 2 | 136, 105, 30, 221, 119 |
| 3 | 68, 105, 15, 221, 119 |
| 5 | 68, 35, 5, 221, 119 |
| 7 | 68, 7, 1, 221, 119 |
| 17 | 68, 1, 1, 221, 17 |
| 4, 1, 1, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 17 x 4 x 1 x 1 x 13 x 1 = 742560
Therefore, the lowest common multiple of 544,210,120,221,238 is 742560.
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.
544 x 210 x 120 x 221 x 238 = 721055462400
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.
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
221 : 1, 13, 17, 221
238 : 1, 2, 7, 14, 17, 34, 119, 238
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 544,210,120,221,238, is 1.
Now, the common factors can be found like this.
544:2x 2x 2x 2x 2x 17
210:2x 3x 5x 7
120:2x 2x 2x 3x 5
221:13x 17
238:2x 7x 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 2x 3x 5x 7x 17x 17 = 971040
Therefore, the value for common factors is 971040.
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 = 721055462400/(1x971040)
LCM = 721055462400/971040
LCM = 742560
Thus, we can understand that the LCM of 544,210,120,221,238 is 742560.
