Given numbers are 946,998,172,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,998,172,765 is 722242620.
Find LCM of 946,998,172,765 with Prime Factorization
| 2 | 946, 998, 172, 765 |
| 43 | 473, 499, 86, 765 |
| 11, 499, 2, 765 |
Multiply the prime numbers at the bottom and the left side.
2 x 43 x 11 x 499 x 2 x 765 = 722242620
Therefore, the lowest common multiple of 946,998,172,765 is 722242620.
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.
946 x 998 x 172 x 765 = 124225730640
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.
946 : 1, 2, 11, 22, 43, 86, 473, 946
998 : 1, 2, 499, 998
172 : 1, 2, 4, 43, 86, 172
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,998,172,765, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
998:2x 499
172:2x 2x 43
765:3x 3x 5x 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 43 = 172
Therefore, the value for common factors is 172.
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 = 124225730640/(1x172)
LCM = 124225730640/172
LCM = 722242620
Thus, we can understand that the LCM of 946,998,172,765 is 722242620.
