Find LCM of 220,162,639,405,559 with Prime Factorization
| 2 | 220, 162, 639, 405, 559 |
| 3 | 110, 81, 639, 405, 559 |
| 3 | 110, 27, 213, 135, 559 |
| 3 | 110, 9, 71, 45, 559 |
| 3 | 110, 3, 71, 15, 559 |
| 5 | 110, 1, 71, 5, 559 |
| 22, 1, 71, 1, 559 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 5 x 22 x 1 x 71 x 1 x 559 = 707257980
Therefore, the lowest common multiple of 220,162,639,405,559 is 707257980.
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.
220 x 162 x 639 x 405 x 559 = 5155910674200
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
639 : 1, 3, 9, 71, 213, 639
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
559 : 1, 13, 43, 559
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,162,639,405,559, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
162:2x 3x 3x 3x 3
639:3x 3x 71
405:3x 3x 3x 3x 5
559:13x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3x 3x 5 = 7290
Therefore, the value for common factors is 7290.
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 = 5155910674200/(1x7290)
LCM = 5155910674200/7290
LCM = 707257980
Thus, we can understand that the LCM of 220,162,639,405,559 is 707257980.
