Given numbers are 873,894,644,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 873,894,644,756 is 251308764.
Find LCM of 873,894,644,756 with Prime Factorization
| 2 | 873, 894, 644, 756 |
| 2 | 873, 447, 322, 378 |
| 3 | 873, 447, 161, 189 |
| 3 | 291, 149, 161, 63 |
| 7 | 97, 149, 161, 21 |
| 97, 149, 23, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 97 x 149 x 23 x 3 = 251308764
Therefore, the lowest common multiple of 873,894,644,756 is 251308764.
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.
873 x 894 x 644 x 756 = 379978851168
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.
873 : 1, 3, 9, 97, 291, 873
894 : 1, 2, 3, 6, 149, 298, 447, 894
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 873,894,644,756, is 1.
Now, the common factors can be found like this.
873:3x 3x 97
894:2x 3x 149
644:2x 2x 7x 23
756:2x 2x 3x 3x 3x 7
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 2x 3x 3x 3x 7 = 1512
Therefore, the value for common factors is 1512.
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 = 379978851168/(1x1512)
LCM = 379978851168/1512
LCM = 251308764
Thus, we can understand that the LCM of 873,894,644,756 is 251308764.
