Find LCM of 221,145,663,595,657 with Prime Factorization
| 3 | 221, 145, 663, 595, 657 |
| 5 | 221, 145, 221, 595, 219 |
| 13 | 221, 29, 221, 119, 219 |
| 17 | 17, 29, 17, 119, 219 |
| 1, 29, 1, 7, 219 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 17 x 1 x 29 x 1 x 7 x 219 = 147374955
Therefore, the lowest common multiple of 221,145,663,595,657 is 147374955.
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 145 x 663 x 595 x 657 = 8305315589025
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
145 : 1, 5, 29, 145
663 : 1, 3, 13, 17, 39, 51, 221, 663
595 : 1, 5, 7, 17, 35, 85, 119, 595
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,145,663,595,657, is 1.
Now, the common factors can be found like this.
221:13x 17
145:5x 29
663:3x 13x 17
595:5x 7x 17
657:3x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13x 17x 17 = 56355
Therefore, the value for common factors is 56355.
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 = 8305315589025/(1x56355)
LCM = 8305315589025/56355
LCM = 147374955
Thus, we can understand that the LCM of 221,145,663,595,657 is 147374955.
