Given numbers are 831,634,168,951
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,634,168,951 is 14751912.
Find LCM of 831,634,168,951 with Prime Factorization
| 2 | 831, 634, 168, 951 |
| 3 | 831, 317, 84, 951 |
| 317 | 277, 317, 28, 317 |
| 277, 1, 28, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 317 x 277 x 1 x 28 x 1 = 14751912
Therefore, the lowest common multiple of 831,634,168,951 is 14751912.
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.
831 x 634 x 168 x 951 = 84174409872
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.
831 : 1, 3, 277, 831
634 : 1, 2, 317, 634
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
951 : 1, 3, 317, 951
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,634,168,951, is 1.
Now, the common factors can be found like this.
831:3x 277
634:2x 317
168:2x 2x 2x 3x 7
951:3x 317
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 317 = 5706
Therefore, the value for common factors is 5706.
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 = 84174409872/(1x5706)
LCM = 84174409872/5706
LCM = 14751912
Thus, we can understand that the LCM of 831,634,168,951 is 14751912.
