Find LCM of 309,182,993,714,221 with Prime Factorization
| 2 | 309, 182, 993, 714, 221 |
| 3 | 309, 91, 993, 357, 221 |
| 7 | 103, 91, 331, 119, 221 |
| 13 | 103, 13, 331, 17, 221 |
| 17 | 103, 1, 331, 17, 17 |
| 103, 1, 331, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 17 x 103 x 1 x 331 x 1 x 1 = 316451226
Therefore, the lowest common multiple of 309,182,993,714,221 is 316451226.
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.
309 x 182 x 993 x 714 x 221 = 8811900839196
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.
309 : 1, 3, 103, 309
182 : 1, 2, 7, 13, 14, 26, 91, 182
993 : 1, 3, 331, 993
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,182,993,714,221, is 1.
Now, the common factors can be found like this.
309:3x 103
182:2x 7x 13
993:3x 331
714:2x 3x 7x 17
221:13x 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 3x 3x 7x 13x 17 = 27846
Therefore, the value for common factors is 27846.
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 = 8811900839196/(1x27846)
LCM = 8811900839196/27846
LCM = 316451226
Thus, we can understand that the LCM of 309,182,993,714,221 is 316451226.
