Given numbers are 705,473,860,732
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,473,860,732 is 81365460.
Find LCM of 705,473,860,732 with Prime Factorization
| 2 | 705, 473, 860, 732 |
| 2 | 705, 473, 430, 366 |
| 3 | 705, 473, 215, 183 |
| 5 | 235, 473, 215, 61 |
| 43 | 47, 473, 43, 61 |
| 47, 11, 1, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 43 x 47 x 11 x 1 x 61 = 81365460
Therefore, the lowest common multiple of 705,473,860,732 is 81365460.
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.
705 x 473 x 860 x 732 = 209922886800
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
473 : 1, 11, 43, 473
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,473,860,732, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
473:11x 43
860:2x 2x 5x 43
732:2x 2x 3x 61
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 5x 43 = 2580
Therefore, the value for common factors is 2580.
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 = 209922886800/(1x2580)
LCM = 209922886800/2580
LCM = 81365460
Thus, we can understand that the LCM of 705,473,860,732 is 81365460.
