Find LCM of 910,454,123,490,221 with Prime Factorization
| 2 | 910, 454, 123, 490, 221 |
| 5 | 455, 227, 123, 245, 221 |
| 7 | 91, 227, 123, 49, 221 |
| 13 | 13, 227, 123, 7, 221 |
| 1, 227, 123, 7, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 13 x 1 x 227 x 123 x 7 x 17 = 3023565090
Therefore, the lowest common multiple of 910,454,123,490,221 is 3023565090.
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.
910 x 454 x 123 x 490 x 221 = 5502888463800
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.
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
454 : 1, 2, 227, 454
123 : 1, 3, 41, 123
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,454,123,490,221, is 1.
Now, the common factors can be found like this.
910:2x 5x 7x 13
454:2x 227
123:3x 41
490:2x 5x 7x 7
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 2x 5x 7x 13 = 1820
Therefore, the value for common factors is 1820.
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 = 5502888463800/(1x1820)
LCM = 5502888463800/1820
LCM = 3023565090
Thus, we can understand that the LCM of 910,454,123,490,221 is 3023565090.
