Given numbers are 681,126,651,322,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,126,651,322,923 is 18822947598.
Find LCM of 681,126,651,322,923 with Prime Factorization
| 2 | 681, 126, 651, 322, 923 |
| 3 | 681, 63, 651, 161, 923 |
| 7 | 227, 21, 217, 161, 923 |
| 227, 3, 31, 23, 923 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 227 x 3 x 31 x 23 x 923 = 18822947598
Therefore, the lowest common multiple of 681,126,651,322,923 is 18822947598.
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.
681 x 126 x 651 x 322 x 923 = 16601839781436
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.
681 : 1, 3, 227, 681
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
651 : 1, 3, 7, 21, 31, 93, 217, 651
322 : 1, 2, 7, 14, 23, 46, 161, 322
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,126,651,322,923, is 1.
Now, the common factors can be found like this.
681:3x 227
126:2x 3x 3x 7
651:3x 7x 31
322:2x 7x 23
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 7 = 882
Therefore, the value for common factors is 882.
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 = 16601839781436/(1x882)
LCM = 16601839781436/882
LCM = 18822947598
Thus, we can understand that the LCM of 681,126,651,322,923 is 18822947598.
