Given numbers are 656,737,172,473
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 656,737,172,473 is 20789296.
Find LCM of 656,737,172,473 with Prime Factorization
| 2 | 656, 737, 172, 473 |
| 2 | 328, 737, 86, 473 |
| 11 | 164, 737, 43, 473 |
| 43 | 164, 67, 43, 43 |
| 164, 67, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 43 x 164 x 67 x 1 x 1 = 20789296
Therefore, the lowest common multiple of 656,737,172,473 is 20789296.
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.
656 x 737 x 172 x 473 = 39333348032
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.
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
737 : 1, 11, 67, 737
172 : 1, 2, 4, 43, 86, 172
473 : 1, 11, 43, 473
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,737,172,473, is 1.
Now, the common factors can be found like this.
656:2x 2x 2x 2x 41
737:11x 67
172:2x 2x 43
473:11x 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 2x 11x 43 = 1892
Therefore, the value for common factors is 1892.
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 = 39333348032/(1x1892)
LCM = 39333348032/1892
LCM = 20789296
Thus, we can understand that the LCM of 656,737,172,473 is 20789296.
