Given numbers are 497,204,723,940,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 497,204,723,940,221 is 74647421940.
Find LCM of 497,204,723,940,221 with Prime Factorization
| 2 | 497, 204, 723, 940, 221 |
| 2 | 497, 102, 723, 470, 221 |
| 3 | 497, 51, 723, 235, 221 |
| 17 | 497, 17, 241, 235, 221 |
| 497, 1, 241, 235, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 497 x 1 x 241 x 235 x 13 = 74647421940
Therefore, the lowest common multiple of 497,204,723,940,221 is 74647421940.
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.
497 x 204 x 723 x 940 x 221 = 15228074075760
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.
497 : 1, 7, 71, 497
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
723 : 1, 3, 241, 723
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 497,204,723,940,221, is 1.
Now, the common factors can be found like this.
497:7x 71
204:2x 2x 3x 17
723:3x 241
940:2x 2x 5x 47
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 3x 17 = 204
Therefore, the value for common factors is 204.
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 = 15228074075760/(1x204)
LCM = 15228074075760/204
LCM = 74647421940
Thus, we can understand that the LCM of 497,204,723,940,221 is 74647421940.
