Find LCM of 524,231,220,945 with Prime Factorization
| 2 | 524, 231, 220, 945 |
| 2 | 262, 231, 110, 945 |
| 3 | 131, 231, 55, 945 |
| 5 | 131, 77, 55, 315 |
| 7 | 131, 77, 11, 63 |
| 11 | 131, 11, 11, 9 |
| 131, 1, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 11 x 131 x 1 x 1 x 9 = 5446980
Therefore, the lowest common multiple of 524,231,220,945 is 5446980.
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.
524 x 231 x 220 x 945 = 25165047600
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.
524 : 1, 2, 4, 131, 262, 524
231 : 1, 3, 7, 11, 21, 33, 77, 231
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 524,231,220,945, is 1.
Now, the common factors can be found like this.
524:2x 2x 131
231:3x 7x 11
220:2x 2x 5x 11
945:3x 3x 3x 5x 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 3x 5x 7x 11 = 4620
Therefore, the value for common factors is 4620.
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 = 25165047600/(1x4620)
LCM = 25165047600/4620
LCM = 5446980
Thus, we can understand that the LCM of 524,231,220,945 is 5446980.
